Placid Industries H35 Hysteresis Brake H35

Description
Torque is proportional to input current, and independent of RPM. Torque is especially smooth, even at near-zero RPM. Also good for light tension / high RPM applications, due to good heat dissipation ratings. All models except H3 have the Cog-Buster which keeps slip torque smooth. Torque is produced without friction plates or magnetic particles. Life is extremely long, even at high RPM, because torque is produced magnetically across an air gap. Slip torque is extremely smooth, even down to zero RPM. Placid Industries' Cog-Buster automatically de-cogs the brake within one revolution of the shaft. 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 continuously. When the load torque is increased, the brake will slip smoothly at the torque level set by the coil input current. Not suitable for precise positioning applications

Datasheet
Datasheet Summary
Powered by GS/AI

The H35 hysteresis brake provides torque proportional to input current, independent of RPM, with smooth slip down to zero RPM via an auto-decogging feature. Torque ranges from 0.6 to 35 oz.-in., with a maximum RPM of 8000 and a 20 ms response time. Maximum heat dissipation is 15 watts with the cover, 25 watts without; case temperature must not exceed 180°F. Maximum overhung load is 5 lb. Shaft inertia is 92 × 10⁻⁶ lb.-in.-sec² and weight is 2 lb. A constant-current DC power supply is required for stable torque control. The shaft rotates freely without excitation. Install with a flexible coupling, precise alignment, and ground the housing.
