Speed controllers come in all shapes and sizes. Depending on the application, as to which one you will use.

Some common types of controllers.....

Brushed motors

Series Wound

Permanent magnet

Brushless motors

Brushless DC permanent magnet

AC induction

Brushed motor controller

KDH-E - High Power Opto-Isolated Brushed DC Series/PM Controller

Voltage 24 - 144v (depending on model)

Continuous Current 180 - 360A (depending on model)

Peak Current up to 800A (depending on model)

supports regen braking on permanent magnet motors
