New 52mm Brushless DC (BLDC) motor design

Maxon motors new optimisation of the High Torque 52mm brushless motor gives even greater performance.

Maxon EC-i 52mm BLDC Servo Motor

Maxon EC-i 52mm BLDC Servo Motor

The EC-i 52mm brushless DC motor from maxon has had the iron-wound internal rotor motor redesigned from 7 pole pairs to 8 pole pairs. This significantly reduces the vibration and noise output of the DC motor. Available in three voltage outputs, 18, 24 and 48V the 52mm 180 W brushless DC motors produce up to 6,000 rpm.

With a correspondingly optimised magnet ring, the brushless EC-i motors with iron windings offer a very high torque density and a low cogging torque. The multi-pole internal rotor is extremely dynamic. It has a solid design, with a welded stainless steel flange and housing, making this brushless DC motor suitable for a wide range of applications such as rotary actuators, valves, robotic joints and process control.

SilverMax NEMA 23 Frame Direct Drive Series by QuickSilver Controls Inc.

QuickSilver Controls, Inc.  is proud to introduce a new full range of NEMA 23 frame Direct Drive Hybrid Servo Motors .  Four stack sizes provide 80 oz-in (.56 Nm) through 430 oz-In (3 Nm) continuous torque, with top speeds from 1000 – 4000 RPM.

QuickSilver Controls SilverMax Motors

QuickSilver Controls SilverMax Motors

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.

Theory, Application & Operation of Frameless Motor Technology. Live Webinar.

February 23, 2016  11:00 AM ET

Register to watch the webinar on or after February 23.

For many years there seems to have been an engineering mystique surrounding the integration of frameless motor part sets into high performance machine design. This has kept many machine design engineers from jumping in to embed these power and torque dense motor types into their applications.

This webinar will focus on the integration of frameless motors into practical machine design challenges. We will touch on the background and use of embedded motor components, typical application overview, performance improvement expectations, typical design and installation best practices, drive amplifier and feedback considerations, and machine system thermal concerns.

We will also review some basic tools available to help design engineers optimize frameless motor performance in customer machine applications.
