Introduction
When production lines demand faster cycles and lower energy bills, the Mitsubishi HG-MR13B servo motor provides a cost-effective solution. This small-capacity, ultra-low inertia motor from the HG Series is engineered to reduce power consumption while boosting throughput. With a rated output of 0.1 kW and a maximum speed of 6000 r/min, it delivers precise motion control without wasting energy.
Technical Specifications Breakdown
Rated Output and Speed
The HG-MR13B operates at a rated output of 0.1 kW and a rated speed of 3000 r/min. This combination allows the motor to handle moderate loads efficiently, consuming only the power needed for the task. The maximum speed of 6000 r/min enables rapid positioning, cutting cycle times and improving overall equipment effectiveness (OEE).
Torque and Current
Rated torque stands at 0.32 Nm, sufficient for steady-state operations, while maximum torque reaches 0.95 Nm for short bursts under heavy demand. The rated current of 0.9A and maximum current of 2.5A ensure the motor operates within safe thermal limits, reducing the risk of overheating and extending service life. Lower current draw translates directly to reduced energy costs over the motor's lifespan.
Inertia and Brake
Ultra-low inertia minimizes the energy required to accelerate and decelerate the rotor, making the HG-MR13B ideal for applications with frequent start-stop cycles. The included electromagnetic brake provides reliable holding torque without additional power consumption, preventing load drift and enhancing safety. Note that an oil seal is not included, so the motor is best suited for clean, dry environments.
Industry Applications
Pick-and-Place Machines
In high-speed pick-and-place systems, the HG-MR13B's ultra-low inertia allows rapid acceleration and deceleration, reducing cycle time by up to 15% compared to standard inertia motors. Lower current draw means less heat generation, cutting cooling costs and improving machine reliability.
Small Conveyor Drives
For small conveyor indexing applications, the 0.1 kW rated output provides ample torque for light loads while the electromagnetic brake ensures precise stopping. The straight shaft simplifies mounting, reducing installation labor costs.
Installation and Setup Guidance
Mount the HG-MR13B using the straight shaft with a compatible coupling. Ensure the mounting surface is flat and rigid to prevent vibration. Connect the motor to a Mitsubishi servo drive (e.g., MR-J4 series) using the appropriate cable. Verify that the electromagnetic brake wiring is correctly polarized to avoid damage. Always follow the manufacturer's torque specifications for shaft connections.
Maintenance and Reliability
Regularly inspect the motor for dust accumulation on the housing, as the lack of an oil seal means contaminants can enter. Check the brake operation monthly by verifying holding torque. The ultra-low inertia design reduces mechanical stress on bearings, extending maintenance intervals. By keeping the motor clean and ensuring proper ventilation, you can achieve a service life exceeding 20,000 hours, lowering total cost of ownership.
Buying Guide
Before ordering the Mitsubishi HG-MR13B, confirm that your application requires ultra-low inertia and small capacity. Verify compatibility with your servo drive and controller.

Frequently Asked Questions
Q: Does the HG-MR13B include an oil seal?
A: No, the HG-MR13B does not include an oil seal. It is designed for clean, dry environments. If your application involves oil or coolant mist, consider adding an external seal or selecting a motor with an integrated oil seal.
Q: What is the maximum torque of the HG-MR13B?
A: The maximum torque is 0.95 Nm, available for short-duration overloads. This allows the motor to handle peak loads during acceleration or momentary jams without oversizing.
Q: Can the HG-MR13B be used with a third-party servo drive?
A: While the motor is optimized for Mitsubishi drives, it can be used with compatible third-party drives that support the appropriate feedback and power ratings. Consult SpareTechPLC for integration support.
Q: How does ultra-low inertia reduce energy costs?
A: Ultra-low inertia requires less torque to accelerate and decelerate the rotor, reducing peak current draw. This lowers energy consumption by up to 10% in cyclic applications compared to standard inertia motors.
Q: What is the weight of the HG-MR13B?
A: The motor weighs 1.50 lbs (0.68 kg), making it easy to handle and mount in space-constrained assemblies.
