Types of Motors

Induction Motors & Gear Motors

Electromagnetic Brake Motors & Gear Motors

Gear Motors & Induction Motors Electromagentic Brake Gear Motors and Induction Motors

Induction motors are optimal for uni-directional operation such as a conveyor system.

These motors utilize a power off activated type electromagnetic brake. Since the electromagnetic brakes exert holding power even when the power is off, they are highly suitable for use as emergency brakes.
