Demag Conical Rotor Brake Motors

Horsepower range from .6 to 68

The unique Demag Conical Rotor Brake Motor (type KB) incorporates the brake as an integral art of the conical sliding rotor. When the motor is at rest, a spring acts on the sliding rotor and forces the brake ring against the brake cap in the motor, holding the rotor stationary. When the motor is energized, its magnetic field generates both an axial and a radial component. The axial component overcomes the spring force, releasing the brake; while the radial component causes the rotor to turn. There is no additional brake control required.

The high starting torque and low inertia of the Demag Conical Rotor Brake Motor has proven to be ideal for the demands of high cycle dynamic drives in literally thousands of applications since the motor was introduced over 50 years ago.

This conical rotor design is produced with optional torque characteristics and various speed configurations, as single-speed or two speed motors that are designed for coupling to Demag Gearmotor System gearboxes. These motors are manufactured in IEC frame sizes 71 through 225 and develop from fractional up to 68 hp at 100% continuous-duty. They are rated at up to 113 hp for intermittent-duty applications. Conical Rotor Brake Motors are also used to power Demag Microspeed Drives.
