Placid Ind. Specifications

Placid Industries - - Magnetic Particle Brakes, up to 25 Newton-meters torque.

Magnetic Particle Brake - Specifications		Larger brakes up to 400 Newton-meters. available.
Torque range = 0-0.7 to 2500 Newton-cm. View in inch units

	Typical applications: Adjustable tension - for unwinding (payout) webs Load simulation - for testing stepper motors, gear motors and mechanisms Soft stops The cross-section drawing shows how brakes work.
	Mount with shaft in any orientation.
Models B5Z-1, B150-H, B1-2

Torque is -

Proportional to input current
Independent of RPM

Characteristics - With no electrical excitation, the shaft freely rotates.
With electrical excitation, the shaft becomes coupled to the case.

While the load torque is less than the output torque, the shaft won't rotate.
When the load torque is increased, the brake will slip smoothly at the torque level set by the coil input current.

Use the sizing information to select the proper brake.
