Magnetic Brakes

Danaher Motion (Wood Dale, IL) released the Thomson-Deltran Power-Off Magnetic Brake (PMB) series of power-off DC, spring-set, multifunctional brakes. Nine standard frame sizes from 30 to 120 are available. Torque range is 45 lb-in to 4,250 lb-in (5 to 48 Nm), in diameters from 3.30 to 11.89". Operating voltages of 24, 90, and 190 VDC are standard (other voltages are available on request). An adjustment collar allows brake torque to be varied, and the fully potted coils come under class “F” insulation.

Rotating Torque Sensor

The Model 01424 rotating torque sensor from Sensor Developments (Lake Orion, MI) uses a shaft-to-shaft configuration for in-line placement, and incorporates a digital non-contact wireless system that provides power to the rotating electronics mounted on the shaft, transmitting the signal back to the receiver in digital format. The torque signal is then represented as a calibrated, high level analog voltage.
