Series 321 provides dynamic stopping or holding torque in a compact package. Mounts to NEMA 56C motors.
Fixed air gap design
Optional AC Rectifiers - internal, or external in-line (availability depends on size)
Class B temperature rise with Class H mag wire
Optional “double D” friction discs are available in 3-7 lb-in dynamic and 3-15 lb-in holding brakes. DD shafts fit the brake directly without a brake hub, no shaft keyway cost and simplify assembly
UR and CUR recognized insulation system - File E-125303; and sizes 1.8 & 2.8 brakes and 48C & 56C motor frame brakes with internal power supply File E-71115
For applications requiring faster reaction time we also offer a quick set rectifier option
