Product Overview

The Mitsubishi HG-MR23B is a brushless AC servo motor from the HG Series. This motor delivers precise motion control for small-capacity applications. It features ultra-low inertia for rapid acceleration and deceleration. The device includes an electromagnetic brake for reliable stopping. You can use this motor for conveyors, pick-and-place machines, and light automation.

Technical Specifications

The Mitsubishi HG-MR23B provides a rated output of 0.2 kW. It operates at a rated speed of 3000 r/min. Rated torque is 0.64 Nm, while maximum torque reaches 1.9 Nm for peak loads.

Key technical parameters include:

• Rated Current: 1.5 A

• Maximum Current: 5.3 A

• Voltage Class: 200VAC Class

• Inertia Type: Ultra-Low Inertia

• Capacity: Small Capacity

• Shaft Shape: Standard

• Electromagnetic Brake: Included

• Oil Seal: Not included

The motor weighs 4.54 kg (10.00 lbs). It operates on a standard 200VAC electrical system.

Performance Characteristics

The HG-MR23B excels in applications needing fast response times. Its ultra-low inertia design minimizes mechanical lag between command and motion. The motor handles moderate loads with its 0.64 Nm rated torque continuously. For peak demands during acceleration, it delivers 1.9 Nm of maximum torque.

The rated speed of 3000 r/min suits most industrial automation tasks. The brushless design eliminates brush wear and reduces maintenance. The electromagnetic brake holds position securely when power is removed. This feature adds safety for vertical axis applications.

Installation Guidelines

Follow these steps for proper installation:

1. Mount the HG-MR23B on a flat, rigid mounting surface.

2. Align the standard shaft with your coupling or pulley.

3. Connect the 200VAC power leads following local codes.

4. Wire the electromagnetic brake to a separate control circuit.

5. Connect the encoder feedback cable to your amplifier.

6. Test rotation direction before applying full load.

Note that this motor has no oil seal. Avoid installation in oily or wet environments. Use protective shaft covers if needed for your application.

Common FAQs

Q1: What is the difference between rated and maximum torque?
A: Rated torque (0.64 Nm) is available continuously. Maximum torque (1.9 Nm) is for short acceleration or emergency stops only.

Q2: Does the HG-MR23B work without the electromagnetic brake?
A: The brake is built into this model. You cannot remove it. Order the HG-MR23 (without B suffix) for a brake-less version.

Q3: Can I use this motor in a washdown environment?
A: The HG-MR23B has no oil seal and no special ingress protection. Use an enclosed gearhead for washdown applications.

Q4: What amplifier is compatible with this servo motor?
A: Use Mitsubishi's MR-J4-20A or MR-J5-20A series amplifiers. Match the 1.5 A rated current for proper tuning.

Q5: Why does the HG-MR23B weigh 4.54 kg while smaller models weigh less?
A: The weight includes the electromagnetic brake and larger magnets. The 0.2 kW output requires more copper and iron than 0.1 kW models.
