- Adjustable tension - for unwinding (payout) webs
- Load simulation - for testing stepper motors, gear motors and mechanisms
- Soft stops

Typical applications:
|
| Models B5Z-1, B150-HA, B1-2 |
 |
Torque is -
While the load torque is less than the output torque, the brake shaft won't rotate. When the load torque is increased, the brake will slip smoothly at the torque level set by the input coil current. Use the sizing information to select the proper brake. |
