The HG-MR13 is a servo motor from Mitsubishi's HG-MR series, classified as Ultra-Low inertia/Small capacity. It delivers a rated output of 0.1 kW at a rated speed of 3000 r/min, placing it in the smallest power tier of the family — sized for light positioning axes, small pick-and-place arms, or tension-control stages where the load inertia is low and acceleration matters more than raw torque. This variant includes an electromagnetic brake (suffix B), which holds the motor shaft at rest when power is removed. On a 0.1 kW frame the brake adds axial length and a DC power requirement; verify the holding torque against the static load before specifying, because the brake is sized for the motor's own rated torque, not for an external overhung load.
Integration Notes
The 3000 r/min rated speed is typical for a small-capacity servo running on a 200 V-class drive. If the application runs below 500 r/min for extended periods, check the continuous torque derating curve — the motor's cooling fan (if shaft-mounted) loses efficiency at low speed, and the brake's duty cycle may need to be factored in.
