Universal Robots says direct torque control has potential for cobot applications such as assembly and screwdriving.

Abstract: Recent investigations have thrown light on the hither to obscure causes of “cusps” in the speed-torque curves of polyphase induction motors, causing the motors to “crawl” at reduced speed or ...

The performance of any EV is affected by the electrical motor specifications and is determined by the torque-versus-speed and power-versus-speed curves of the motor ... asynchronous or induction ...

Solid rotor induction motors (SRIMs ... input power, shaft torque, speed and winding temperature are measured. After the load test, the motor is uncoupled from the dynamometer and a no-load test is ...

These losses depend primarily on the magnetic induction ... torque decreases when speed increases. This graph shows the effect of iron losses on the power curve of a BLDC motor, the Portescap ...

The speed of this rotating magnetic field is called the ... Therefore, at high slip values, an induction motor's torque-slip curve is shaped like a rectangular hyperbola and passes through the point ...

Induction motors are known as asynchronous motors because the induced EMF and the rotating torque that comes with it can exist only when the rotor's speed lags behind the RMF. Such motors are ...
