The S90MPA-B34D50H38 is a magnetic particle brake for tensioning, locking, and motor testing applications, featuring a 24V DC coil and a shaft mounted on one end. It has a maximum torque range of 0.6-35 lbf·in, an electrical power dissipation of 9 watts, a maximum shaft speed of 1800 rpm, and a maximum overhung load of 35 lbf. The brake has a maximum unforced response time of 30 msec and a rotational inertia of 12 × 10⁻⁵ lb·in·sec². It weighs 4.0 lb and is mounted with four #10-32 fasteners on a 3.000 inch bolt circle. Its dimensions are 0.375 inch bore diameter, 0.4980 inch outer diameter, 2.20 inch length, with overall width of 1.47 inch, clearance of 0.25 inch, and flange height of 0.47 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.
