Highly Dynamic DC Brushless Servo Motor – maxon’s EC-i40

Compact And Powerful

In automation and robotics, many applications are characterized by high energy and high torque at the same time.  Spatial restrictions also mean that drives must be short, have a long service life and be maintenance-free.  The newly redesigned EC-i motors from maxon motors offer solutions that fit these requirements perfectly.

maxon's EC-4pole 32 HD

maxon’s EC-4pole 32 HD

The Heavy Duty Motor EC 22 HD, innovation of the year in 2010, has now been joined by a larger and more powerful version. The new, electronically commutated EC-4pole 32 HD motor has all the features of the award-winning 22 mm motor.  It is designed for extremely rough operating conditions, particularly applications in deep drilling.

Deep drilling technology (called “downhole drilling” in the field of oil and gas exploration) makes it possible to recover oil and gas from depths of more than 2500 m. By combining deep drilling with directional drilling (dynamic position alignment of a bore in the earth), previously unreachable oil reserves are being opened up, with drilling depths of approx. 5000 m and drill lengths of up to 11000 m.  The development of specialized electronics and drives has made it possible to better monitor and control many functions across the entire drilling process.  For instance, it is now possible to dynamically measure and adjust the position of the drill head during the drilling process.  Diverse deep drilling tools also use hydraulic valves or flaps that are operated by electromechanical drives.  The temperatures and pressures at these depths, combined with the strong vibrations that occur during the drilling work, present unique challenges for the use of electronic drives.

The different versions of the EC-4pole 32 HD are designed for operation in air or in oil (flooded in hydraulic oil).  The power rating depends on the surrounding medium and amounts to 220 W in air and, due to the much higher heat flow, 480 W in oil.  They are designed for ambient temperatures of more than 200 °C and atmospheric pressures of up to 1700 bar.  The Ø 32 mm motors must also be able to withstand vibrations of up to 25 grms as well as impacts of up to 1000 G (1000 times the acceleration due to gravity at the earth’s surface).  As an example, a Formula 1 vehicle is exposed to approximately 2 G and fighter jets are exposed to approxi-mately 13 G.  The motors feature high efficiency (up to 89% in air, more than 80% in oil), making them ideal for use in battery-operated applications.  With their detent-free running properties, they have excellent control characteristics and are suitable for high-precision positioning tasks in outer space, even at low speeds.

The EC-4pole 32 HD is ideal for use in environments with extreme temperatures, subject to high vibration, or under ultra-high vacuum.  This means the motors can also be used in aerospace applications, e.g. for gas turbine starters, for the generators of jet engines, for regulating combustion engines, or for exploration robots.  For the use of the motor in conjunction with a gearhead, maxon offers the GP 32 HD, a powerful and robust planetary gearhead.

TBW Series Iron Core Linear Motor from Tecnotion

The TBW series is the water cooled variant of the TB series.  It features a fully integrated, highly efficient cooling system which enables the TBW to reach even higher continuous forces than the standard version and sustain extreme accelerations while maintaining its submicron position accuracy.  Since heat is not dissipated into the machine’s construction, it is especially suited for applications where thermal management is an issue.

Tecnotion TBW Linear Motor

Tecnotion TBW Linear Motor

This type of motor has a low magnetic resistance. The ironcore and the magnet closing plate are excellent flux conductors, so only the magnets and a single airgap contribute to the resistance in the circuit.  Due to this low resistance, the ironcore motor’s operation involves a strong flux, yielding high forces and excellent efficiency.  That makes this type a real workhorse with the following main features:

  • high peak force density
  • high continuous force density
  • relatively low heat dissipation

Motion Control for Newbies

Motion Control For Newbies
Check out the latest publication from the maxon academy, Motion Control for Newbies, a practical introduction to motion control.  132 pages.

The basic approach of this textbook, like many, is a practical and experimental one; however, it is reversed from most.  Instead of first explaining the theory of motion control and then applying it to specific examples, here we will start with hands-on experimenting on a real maxon EPOS2 P positioning control system by means of the EPOS Studio software and explain all the relevant motion control principles/features as they appear on the journey.  Therefore, the text contains mainly the exercises and practical work to do.  Background information can be found in the colored boxes.

This is primarily a textbook about motion control and not about programming a PLC. Therefore, the programming part should be considered as an introduction on how to program the motion control aspects.  It is not a full PLC programming course.

Motion control is mechatronics.  It is the combination of mechanics and electronics, of actuators (motors) and sensors all controlled by software.  In this textbook, we identify and define the role, behavior and mutual interaction of the different elements of a motion control system.  However, we need to know the basic internal construction and working principles of the elements only to a limited extent, but rather look at them as a black box.  Given a certain input, what comes out of the box?  How is this output generated and which parameter can be used to influence the output?  For instance, we will not explain how feed forward control must be implemented, but we will explain the basic idea of it and how the parameters will look during axis tuning… click on the link below to download the complete textbook.

New Generation of Hexapedal Robots

Whether traversing over the sands of Mars, or walking up a stone path, this robot was designed to move easily and quickly, to jump, and even to flip over.

The biologically inspired robots being designed at the University of Pennsylvania aim to provide new levels of mobility and durability, while providing the capability for rapid behavior development.  The X-RHex (Robot Hexapod) is the latest version of the highly mobile RHex platform.  X-RHex was designed for greater strength, longer runtime, and more mobility than previous versions, plus it is the first RHex to be built to carry a modular payload architecture to support a wide variety of research requirements.

The six legged robot is modeled after insects where three legs are always touching the ground at the same time. As a running robot, the X-RHex provides robust operation in complex, natural, outdoor terrain. The robot is expected to be an effective research machine for in the laboratory as well as outdoors for field tests.

The payload specifications include a 5V, 12V, and battery voltage (37V to 42V) power interface, and a USB and Ethernet connection.  Payloads are attached to the robot using mil-spec Picatinny rail mounted standard interface.  While typical payloads are often smaller in mass than the X-RHex itself, the robot has been tested for carrying up to 12kg on its back, which is significantly heavier than the weight of the robot. Payloads can include webcams, GPS units, and a secondary computer for fast processing of sensor data.

The X-RHex body is 57 x 39 x 7.5 cm, with a ground clearance of 12.5 cm (12 cm when inverted).  Each leg has a diameter of 17.5 cm, and the unit weights 9.5 kg with both batteries installed.  One of the main objectives for the mechanical design of X-RHex was to improve its frame durability in both resistance to fatigue and impact, as well as serviceability while achieving better performance than past models of RHex.

Leg design, on the other hand, was preserved.  The leg mounts are nearly centered on the thinner body, which means the robot operates with greater ground clearance even when in an inverted state.  The motors were chosen after careful analysis of the performance of past RHex robots.  The team chose to use flat brushless motors designed and manufactured by maxon motor USA. Each motor offers 84 Watts of continuous power, has a gear ratio of 28:1, and a maximum robot power density of 240 W/kg.

UPenn robot_2The X-RHex is designed around four subsystems, including a main computer, electronics stacks, batteries, and motor assemblies.  While the main computer handles all high-level control and communications; the electronics stacks house the motor controller, control interface board, and the battery management board used for power distribution, regulation, protection, and monitoring.  Mounted to the outer side of each stack is a lithium polymer batter and interface board.  A motor assembly, which contains the brushless motor and related sensors, is located at each of the six hips.

X-Rhex travels at a high speed of about four body lengths per second (about two meters per second).  The motors used are maxon EC 45 brushless motors.  There is one located at each of the six C-legs (the leg is shaped like a C).  The C-legs are basically springs, which are compliant in both vertical and rotational direction.  This means that the legs can push even though they rotate.  Brushless motors are perfect for this type of application because they are high-efficiency motors, they have no friction due to the brushes, and produce no sparks while in operation.

maxon designs and manufactures their complete line of both brush and brushless motors in-house.  They also provide gearheads, encoders, and other accessories for their motors, including a wide array of electronics.  The company’s EC flat brushless motors are available in power ratings from 12 to over 70 watts, and come standard with Hall sensors.  The motors are also available in a variety of operating voltages, as well as speeds and torques. maxon motors offer long life and quiet operation.

There are two phases to each leg’s operation: the ground phase and the aerial phase.  Like an insect, three legs are in each phase of operation at any particular time.  This provides static stability for the robot.  The gait is called an alternating tripod gait, and is the most stable operation for a six-legged machine.

The ground phase of the rotation has to move at a slower speed and requires a higher torque rating.  The aerial phase of the rotation needs to move at a faster speed, but requires lower torque.  This is because the legs are on the ground for only about 60 to 90 degrees of rotation, while they are in the air the other 270 to 300 degrees of rotation.

Further, friction is created while the C-leg is in its ground phase no matter what the terrain.  Since the X-RHex can travel over rocks, sand, dirt, grass, the floor of a building, etc., the time the leg spends in the ground phase versus the aerial phase is variable.  Note that not all gaits have to be tripod based, either. But, to be as flexible as possible, different algorithms must be created for each gait dependent upon where the robot is expected to travel.
