The S90MPA-B45D75H50 is a magnetic particle brake designed for precise torque control in tensioning, locking, and motor testing applications. It features a 0.501 inch bore diameter, a 2.63 inch shaft diameter, and a mounting pattern on a 4.228 inch bolt circle. The brake operates on 24V DC and generates a torque range of 1 to 60 lbf-in with a maximum unforced speed of 1800 rpm. It has an electrical power dissipation of 8 watts, a shaft inertia of 45 x 10^-5 lb-in-sec², and a maximum overhung load of 85 lbf. The unit is secured with four #10-32 mounting holes and includes a 3/16 inch keyway and flat oriented at 90 degrees to the shaft keyway.
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.
