That torque density — 85.9 N·m from a 3.0 kW frame — tells you this motor is wound for high torque at low speed, not high-speed spindle work. It pulls 4.8 kVA from the supply at full load, so factor that into the drive sizing and the DC bus capacitance on the servo amplifier side. ## Wiring and termination notes Power and ground conductors (U, V, W) take 3.5 mm² (AWG 12) in a general environment. The electromagnetic brake pair (B1, B2) uses 0.5 mm² (AWG 20). That brake wire gauge is light — verify the brake current draw against the drive's brake output rating; if the cable run exceeds a few metres, step up to 0.75 mm² to keep voltage drop under control during hold.","metaTitle":"Mitsubishi HG-SR301BJK Servo Motor, 3.0 kW, 1000 rpm","metaDescription":"HG-SR301BJK rotary servo motor, 3.0 kW output, 85.9 Nm max torque, 1000 rpm rated speed.
