The S90MPA-B34D50S is a magnetic particle brake designed for tensioning and motor testing applications, with a shaft coupled to the housing via electrical excitation to produce torque proportional to input current. It has a solid shaft with a 1.125-inch diameter, mounted on a 2.000-inch bolt circle, and features four #10-32 mounting holes. The brake operates at a maximum speed of 1800 rpm, delivers a torque range of 0.6 to 35 lbf-in, and handles a maximum overhung load of 35 lbf. It dissipates 9 watts of heat, with an electrical power requirement of 9 watts and a shaft inertia of 12 x 10^-5 lbf-in-sec^2. The unit includes a keyway and flat on the shaft, oriented 90 degrees from the 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.
