Rated speed sits at 3000 r/min, with a maximum speed of 6000 r/min, so it covers the common 3000 rpm base for most servo applications and leaves headroom for high-speed moves when the load allows. ## What the speed ratings mean for fit The 3000 r/min rated speed is the continuous-duty operating point where the motor delivers its full rated torque without overheating. The 6000 r/min maximum is a short-duration ceiling — you can overspeed for brief moves, but the torque drops off above rated speed (constant-power region).","metaTitle":"Mitsubishi HG-KR43-K(B) Rotary Servo Motor, 3000 r/min, 6000","metaDescription":"Mitsubishi HG-KR43-K(B) rotary servo motor, rated speed 3000 r/min, max speed 6000 r/min.
