Description

Designed for high-dynamic, high-precision industrial motion control, the HG-MR73B rotary AC servo motor delivers rapid acceleration and deceleration capabilities within an ultra-low inertia footprint. This 750W power-class actuator integrates directly with Mitsubishi Electric MELSERVO-J4 servo amplifiers, providing high-resolution positioning and robust performance in high-speed machinery. Featuring an integrated electromagnetic brake, this module ensures reliable shaft retention during power-loss or disabled states, making it highly suited for vertical axis control or holding applications.

Features

Ultra-low inertia rotor design optimized for high-frequency start/stop operational profiles.
High-resolution 22-bit absolute/incremental encoder providing 4,194,304 pulses per revolution for exceptional positioning accuracy and velocity smoothness.
Built-in electromagnetic holding brake ("B" suffix) to prevent axis slippage during power cuts.
IP65 environmental protection rating (excluding the shaft-through portion) for resilience in challenging industrial conditions.
Seamless integration with the MELSERVO-J4 amplifier platform via high-speed serial feedback.

Applications

High-speed pick-and-place industrial robotics.
Material handling inserters and packaging machinery.
Semiconductor manufacturing and wafer handling equipment.
X-Y gantry systems and vertical axis positioning assemblies.
Textile feeder and tension control machinery.

Connections and Interfaces

Connection Interface	Function Description
Motor Power Connector	Supplies 3-phase AC power (U, V, W) and protective earth (PE) ground to the motor windings.
Brake Connector	Dedicated 24 VDC input connection to engage/release the internal electromagnetic holding brake.

Installation Guidelines

Mounting Alignment: Ensure precise alignment between the motor shaft and the driven load. Always use flexible couplings to mitigate radial and axial forces beyond specified shaft load limits.
Brake Operation: The electromagnetic brake is strictly designed as a holding brake. Do not use this brake for dynamic braking or deceleration control under normal operating conditions.
Cable Routing: Separate encoder cables from main power and motor drive cables by at least 10 cm to prevent electromagnetic interference (EMI).
Heat Dissipation: Mount the motor in a well-ventilated space, ensuring the surrounding air temperature does not exceed 40 degC during continuous duty cycles.

What is the main function of the electromagnetic brake in the HG-MR73B?

The integrated electromagnetic brake on the HG-MR73B is a holding brake designed to lock the motor shaft in place when power is removed, preventing gravity-fed slippage on vertical axes or unexpected movement during system stops.

Which Mitsubishi servo drives are compatible with the HG-MR73B motor?

The HG-MR73B is fully compatible with Mitsubishi Electric MELSERVO-J4 series amplifiers rated for 750W, including the MR-J4-70A, MR-J4-70B, and MR-J4-70GF units.

Can the HG-MR73B be used in dusty or wet environments?

The HG-MR73B features an IP65 environmental rating, which protects against dust ingress and low-pressure water jets. However, the shaft-through passage is not sealed to IP65, so an oil seal or protection cover must be used if liquid exposure is expected at the shaft.
