Enrico shows how his Infineon TLE94112EL motor controller shield can be put to work through a simple Arduino sketch.

Toshiba launches a three-phase brushless motor control pre-driver IC suited to high-velocity server fans, blowers and pumps.

Toshiba launches a three-phase brushless motor driver IC with a rotation speed control function, for application in small fans.

The crux of closed loop stepper operation is adding an encoder and operating the motor as a commutated two-phase brushless DC motor. The fact that an encoder is needed means that truly low-cost ...

For example, traditional step motor systems run in open loop control. That means the drive electronics continuously supply current to the motor whether or not the load is demanding torque.
