Drives

The drives in this section allow to drive DC and Brushless motors in speed or torque control.

They are chopper drives with 1 or 4 quadrants and one-way current control.

The difference between the 1 or the 4-quadrant drive lies in the possibility to control the motor in the acceleration or deceleration phases.

A specific linear drive is designed to control low inertia (ironless) micromotors; it can avoid the heating of the motor due to the current ripple that all the high frequency chopper drives have.
