A 2-blade cutter head and double-edge carbide blades for added performance and a smooth finish. View All Farm/Agriculture Motors. The first is the time it takes for a coil to develop a magnetic field strong enough to pull in and attract an armature. Simply put if the application torque is lower then the initial out of box torque of the brake, burnishing would not be required; however if the torque required is higher, then burnishing needs to be done. In the maximum torque condition, discs are rotated until the fields are directly opposing each other, so the magnetic fields bump against each other and have to travel circumferentially through the disc putting the maximum amount of magnetic drag on the disc. A typical rule of thumb is that 15 times the normal coil voltage will produce a 3 times faster response time. We'll adjust that between 20 and 30 thousandths. On request, we will gladly deliver our motors and gearmotors with an integrated mechanical brake, which is available as single brake or double brake. equipment beyond the speed reducer output shaft.
