CDI Electromagnetic Power On Brake

Principles of Operation

• When power to the magnetic coil is cut the magnetic field on the yoke collapses and the plate is no longer attracted. It is pulled back by the spring and motion transmission is cut.

• When the magnetic coil is energized the yoke is magnetized and draws the armature plate over. This causes friction between the lining on the yoke and the armature, and the clutch is engaged.

Actions of the brake and spring:

• Fast response: Dry design means instant reaction to commands.

• Durability: Excellent heat dissipation and quality materials mean long life, even under high frequency and high performance conditions.

• Easy to install and maintain: Sealed bearing race eliminates the need for removal the center core. No dust brush is needed, and operation is simpler and easier.

• No adjustment of the motor: The motor is designed so that it does not need adjustment of the friction surface, and once it is installed only very minor adjustments are needed.

• Sure motion: One-piece plate will not slip even under the strongest vibration for longer life.
