The actuator modules are designed to interface with other EMB modules via components mounted to the shaft. Examples of components are gears, pulleys, sprockets, shaft couplers, and shaft collar hubs.

The EMB-AM1, EMB-AM2, EMB-AM3, and EMB-AM4 modules are brushed DC motors. 

The EMB-AM4 (stocked item) is an actuator module, powered by a Swiss made premium quality, high efficiency and low inductance brushed DC motor. There is no internal gearing, the system is direct drive.

The EMB-AM5 is a hysteresis brake, applications include use as a load or disturbance, to characterize actuators and mechanisms such as a dynamometer.

Brushless motor and stepper motor modules are coming soon.
