The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

In some categories of motor drive applications, users have little or no tolerance for unpredictable, uneven, or irregular motor behavior. While this certainly cannot be said of all motor-driven ...

If you have a brushless motor, you have some magnets, a bunch of coils arranged in a circle, and theoretically, all the parts you need to build a rotary encoder. A lot of people have used brushless or ...

Permanent-magnet brushless dc servomotors (PMBDCs) provide the highest continuous torque density and efficiency of any electric motors, which is why they are widespread. However, getting top ...

The motion control specialist's new offerings include integrated‑drive actuators with four‑Wire CANopen and an EtherCAT LPA series.

Quantum Devices Inc. recently announced a new series of miniature incremental optical encoders. Each of the encoders in the QM22 series has a 22-mm diameter and 12.4-mm thickness. According to the ...

It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...

After only a few years of being completely immersed in the culture of motor drivers, it is very easy for me to take for granted the fact that most people are not familiar with electromechanical ...

Roboteq, Inc introduces the HBL2350, an intelligent controller capable of simultaneously driving two brushless DC motor up to 75Amps each at up to 50V. Roboteq's HBL2350 is the world's first dual ...
