Brake photo 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 in any orientation.
Models B5Z-1, B150-H, B1-2  


Torque Curve 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.
