Mitsubishi SF-JRVB Vertical Flange-Mounted Three-Phase Brake Motor for Mixers and Machinery

The Mitsubishi SF-JRVB (SF-JRVB) is a three-phase induction brake motor from the SF-JRVB series, built in a vertical, flange-mounted configuration for mixers and general machine drives. It combines a fully enclosed fan-cooled induction motor with a non-excitation spring-applied brake. Across the series, braking torque spans 2 to 150 N·m and the mechanical brake life is rated at 2 million cycles. Standard motor voltages are 200/200/220 V at 50/60/60 Hz, and the motor protection is IP44 with IP20 at the brake; insulation class is F. The series is designed for ambient temperatures of -20 to 40 °C, humidity up to 95% RH and altitudes up to 1000 m. Available outputs range from 1/4 to 10 hp, with three lead wires on ratings up to 3.7 kW and six lead wires from 5.5 kW; frames up to 132 use a terminal block, while 160-frame units use lugs. The supplied product data lists a 100L frame, 1.5 kW, 1720 rpm and 220 V three-phase rating. Typical uses include mixers and machinery that require flange mounting, high torque and smooth speed.
