Placid Industries H85 Hysteresis Brake H85

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 H85 hysteresis brake provides torque from 3 to 85 oz.-in. proportional to input current, with no mechanical contact and smooth slip even at zero RPM. It operates up to 6000 RPM, dissipates 35 watts with the cover or 60 watts without, and has a maximum case temperature of 180°F. Shaft inertia is 56 × 10⁻⁵ lb.-in.-sec², weight is 4.5 lb, and response time is 40 ms. It requires a constant-current DC power supply and features an auto-decogging mechanism. Available with 12 V, 24 V, or 90 V DC coils, with resistances of 28, 101, and 1300 ohms respectively. Mount with flexible couplings and ground the housing for safety.
