8 BRAKES — Refer to GE for application of brakes rated above 100% of rated motor torque. Order must specify AC/DC voltage and frequency, torque rating (Lb. Ft.), enclosure, and orientation with respect to the motor. Customer is responsible for specifying brake torque rating. GE does not recommend the use of brakes on TEFC Kinamatic motors. When brakes are required, GE recommends TEAO enclosures. 8a BRAKES, DISC TYPE These brakes are applicable for holding service within rating limitations shown in the table on the next page. Where brakes are required for stopping duty, the heat-dissipating capacity may be the determining factor in the brake selection. In such cases, refer to GE. Brakes are continuously rated and are nonadjustable spring set and electrically released. For brakes of a specific manufacturer, nonlisted capacity, or adjustable or electrically set brakes, refer to GE. For frames CD6000-CD6900, use floor-mounted brakes.

Information Outline Dimensions

Disc type brakes — Disc type brakes are commonly used on ratings 250 HP and below. The brakes are continuously rated and can be mounted on CD180AT- CD5010AY frames.

Application

AC brakes are recommended on disc brake applications wherever possible, especially for those applications where high cycling duty may occur (e.g., on hoist or screw-down applications). Use a brake of standard enclosure with dripproof fully guarded or splashproof fully guarded motors, and on TENV and TEAO motors for applications in ambients containing chips and/or non-abrasive, non-conducting, and non-explosive dusts and coolants.
