The S90MPA-B28D37H38 is a magnetic particle brake designed for tensioning and locking applications, with a shaft mounted on one end. It operates on 24V DC and generates torque proportional to input current. The brake has a maximum overhung load of 2.5 lb, a maximum speed of 2000 rpm, and an electrical torque range of 0.3 to 15 lbf·in. It dissipates 6 watts of heat, has a shaft inertia of 34 × 10⁻⁶ lbf·in·sec², and a response time of 20 msec. The unit is mounted with three #8-32 threads on a 2.000-inch bolt circle and weighs 25 lb. Its physical dimensions include a bore diameter of 0.375 inch, an outer diameter of 1.125 inch, and an overall length of 2.87 inch.
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.
