The S90MPA-B47D75H50 is a magnetic particle brake designed for tensioning, locking, and motor testing applications, with a torque range of 2.5-115 lbf·in, maximum speed of 1800 rpm, and maximum overhung load of 8.0 lb. It has an electrical power dissipation of 13 watts and shaft inertia of 61 × 10⁻⁵ lb·in·sec². The brake features a 0.501 inch shaft diameter, 0.7480 inch bore, and mounting holes on a 4.228 inch bolt circle with four #10-32 threads. It operates on 24V DC and has a response time of 55 msec.
Clutches and brakes are essential for the efficient control and transfer of drive torque, speed, and power in many rotational drive systems. Precision brakes and clutches can be used to cease or regulate movement.
A brake is utilized to decrease or halt a load (braking) in a motor (either forward or reverse). The function of a clutch is to disengage a drive shaft, pausing the rotation and transferring torque to an output shaft.
A clutch-brake is a single unit with the two combined functions of clutching and braking.
Brakes and clutches are classified by the method used to disengage or stop rotary motion (i.e., friction, mechanical, or electromagnetic), as well as the operative mechanism used to employ the chosen element (i.e., electrical, mechanical, pneumatic, or hydraulic).
We offer several types of brakes, including permanent magnetic brakes, power-off, power-on, and magnetic particle brakes. We also offer several clutch styles, including roller clutches, slip clutches, and electromagnetic clutch couplings.
