Hybrid Servo motors are very well suited for Direct Drive applications – eliminating the need for gear heads in most applications.  These high torque motors match well to loads in the 500-2000 RPM speed range, typical of lead screws and belt drives, and can provide a significant increase in both power and efficiency over conventional servo motors in these speed ranges.

The PVIA control system includes patented damping methods to allow wide ranges of inertial mismatch without retuning or notch filters, reducing the need for inertial matching of the motor to the load. 100:1 inertial mismatch ratios are easily tuned.

The intuitive command language allows for easy program creation/modification/debug using the free QuickControl® environment available from their web site.  The programming environment provides for two programming threads in addition to an active motion.  Sophisticated programs can be easily implemented. Serial communications include MODBUS® RTU, 8bit ASCII, 9bit binary, and DMX512. CANopen® is simultaneously available with the serial options.

Seven IO are provided for external interfacing.  Programmable terminations allow the IO to be pulled high, pulled low, or floated while in input mode. All of the IO may also be used as analog inputs, with one channel also supporting 0-10v analog control.

Do you know the difference between these 10 types of servomotors?

Servomotors are generally used as a high performance alternative to the stepper motor. Stepper motors have some inherent ability to control position, as they have built-in output steps. This often allows them to be used as an open-loop position control, without any feedback encoder, as their drive signal specifies the number of steps of movement to rotate. This lack of feedback though limits their performance, as the stepper motor can only drive a load that is well within its capacity, otherwise missed steps under load may lead to positioning errors. The encoder and controller of a servomotor are an additional cost, but they optimize the performance of the overall system (for all of speed, power and accuracy) relative to the capacity of the basic motor. With larger systems, where a powerful motor represents an increasing proportion of the system cost, servomotors have the advantage….

maxon’s New BLDC Sterilizable Gearmotor EC 19 and GP 19M

High power up to 120 W, speeds up to 100,000 rpm, sterilizable 1000 times.

Maxon EC19 and GP19M Sterilizable Motor

Maxon EC19 and GP19M Sterilizable Motor

With its modular construction, this new brushless DC motor is available in three performance classes: the cost-optimized EC 19 at 60 Watt, the strong and high-speed EC 19 at 120 Watt and the sterilizable high-end version EC 19 at 120 Watt. The internals of the drives are responsible for their individual characteristics:

  • The EC 19 at 60 W is equipped with a magnetic circuit that is designed for speeds of up to 80,000 rpm. The maximum continuous torque is 12 mNm and the motor contains no Hall sensors.
  • The EC 19 at 120 W has been designed for speeds of up to 100,000 rpm and delivers a high continuous torque of 24 mNm. Versions with and without Hall sensors are available.
  • The EC 19 Sterilizable at 120 W may be sterilized in an autoclave 1000 times. With a maximum permissible speed of 100,000 rpm and 24 mNm continuous torque, this drive also withstands high temperatures and harsh steam cycles. This is achieved through careful selection of materials and through protection of the components such as in the hermetically sealed rotor magnet.

With maxon motor’s winding technology, it is possible to offer various voltage versions. The stator has been designed without slots. Therefore, no cogging torque occurs resulting in excellent control properties and extraordinarily smooth running. Together with an optimally balanced rotor, low-noise and low-vibration operation is easily achieved.

maxon’s new sterilizable planetary gearhead, the GP 19 M is ideal for applications requiring very high speeds – input speeds of up to 40,000 rpm. To accommodate such high speeds, the toothing and materials have been especially designed to minimize friction. A key demand placed on the material is 1000 sterilization cycles. Worth noting is the no-need to disassemble the motor for the sterilization process.   The new 19 mm servo motors are particularly suitable for surgical and dental devices, such as arthroscopic shavers and bone drills. There is also a focus on respirators and CAD/CAM spindle drives.

Three critical factors for servo motor sizing

Reprint of December 30, 2015 Linear Motion Tips article from Design World


Servo motor sizing is often done with the help of a manufacturer’s sizing program, but it’s important to understand the three most critical factors—speed, torque, and inertia—to ensure you select the best-fit motor for the application.

Selecting the right servo motor for a linear motion system is a complex task, beginning with initial assumptions and component selections, which must be checked through a series of calculations and, in most cases, repeated over several iterations until a suitable combination of motor and mechanics is found. Most motor manufacturers offer online sizing tools that make the process easier, ensure that the best components are selected, and help preserve the design engineer’s sanity. But as a designer, or even an end user, it’s important to have an understanding of the three critical parameters of servo motor sizing: inertia, speed, and torque.

KOLLMORGEN AKD SERVO DRIVES AND AKM SERVO MOTORS

Kollmorgen servo drives are used for dynamic motion applications where precise positioning, speed control, or torque efficiency is key. Kollmorgen servo drives range from 300 watts to 50,000 watts of continuous duty power output. Peak outputs Kollmorgen servo drives are impressive with peak operation at 3 times the rated continuous current for a full 5 seconds in certain drives. This is a clear Kollmorgen advantage since many manufacturers can only rate peak operation at 1 second or less. This allows many applications to use significantly smaller servo drives and expands the dynamic performance of the servo drive lineup.

Connectivity is a key aspect in machines so fieldbus options are plentiful. Kollmorgen support many popular ethernet fieldbuses like EtherCAT, Ethernet /IP, Profinet, and SynqNet. Support for traditional fieldbuses is available on certain models as well, including Profibus, Devicenet, CanOpen, RS485, RS232, Sercos II and Sercos III.

New Torque Motor Family from Tecnotion

Tecnotion adds QTR Frameless Torque Motors to its direct drive product offering.  With low axial height and high torque density, the QTR bridges the size-performance gap.

Direct Drive Motors, also know as Torque Motors, are permanent-magnet direct drive motors that rotate along an axis.  They can be used wherever a rotary movement is required and offer numerous advantages over conventional servo drives.

Torque Motors from Tecnotion are extremely compact, provide an extremely stiff drive train, eliminate the need for time-consuming mounting procedures, are virtually maintenance free and can be integrated directly into the machine structure, while the spacious open inner diameter enables wire and cable feedthrough.  To top things off the entire series comes with completely sealed stators and integrated temperature protection and measurement sensors.

Tecnotion QTR

The direct drive technology of brushless torque motors is an ideal way to enhance productivity, accuracy, and dynamic performance of applications.  This technology lowers costs, shrinks space requirements, and reduces wear and tear.  Torque motors eliminate the need for mechanical transmission components such as gearboxes, belts and speed reducers.  This reduces transmission losses and eliminates the cost and maintenance required for additional components.  And because there is no contact between rotor and stator, there is no mechanical wear, meaning less maintenance and longer life.

Tecnotion QTR Product Overview

Tecnotion QTR Product Overview

At first glance the QTR series stands out because of its cast design, which differentiates it from other torque motors by providing a low thermal resistance and very high torque density, as seen in the QTR’s very flat design, large inner diameter and low stator and rotor mass.  All motors come equipped with integrated temperature sensors and high voltage insulation.  Rather than flying leads, the QTR series is provided with braided power and sensor cables with strain relief integrated in the stator housing, reducing the rate of wear and potential failure.

The QTR motor series offers a very flat design for lower axial height and high torque density.  Features such as a large inner diameter, strain-relieved cable exit, integrated temperature sensors, low thermal resistance, and low stator and rotor mass differentiate the QTR products from other torque motors currently available.

With three outer diameters – 105, 133, and 160 mm – and five build heights, ranging from 17 mm to 92 mm, the QTR series suits applications in markets such as Semiconductor, Medical, Machine Tool, Printing, Rotary tables, Factory Automation, and Robotics. Continuous torque ranges from 1.4 to 63.5 Nm, and speed ranges from 190 rpm to 6918 rpm.
