MITSUBISHI HG-H453BS-D48 AC Servo Motor 3500rpm 4.5kW Brake D48

Buy online your MITSUBISHI HG-H453BS-D48 AC Servo Motor from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The MITSUBISHI HG-H453BS-D48 is an AC servo motor from the HG series designed for CNC machine tools and industrial automation applications that require precise motion control and reliable positioning performance. With a power rating of 4.5 kW and a nominal speed of 3500 rpm, it is well suited for feed axes, auxiliary drives, gantry systems, and other demanding motion-control tasks.

This motor is equipped with an integrated holding brake (D48), which helps maintain axis position when power is removed and provides additional safety for vertical axes and load-holding applications. The brake is particularly useful during machine shutdowns, maintenance operations, and emergency stop situations where secure positioning is required.

The HG-H453BS-D48 features an OSA24RS absolute encoder with a resolution of 1,048,576 pulses per revolution, providing highly accurate position feedback for precise servo control and repeatable machine performance. Combined with a compatible MITSUBISHI servo amplifier, the motor delivers smooth low-speed operation, responsive acceleration, and stable torque output across a wide range of operating conditions.

Designed with a 176 mm square flange and a straight shaft, this model is commonly used as a direct replacement motor when the original unit has experienced bearing wear, insulation degradation, brake failure, or connector damage. Matching the exact motor reference ensures compatibility with the existing mechanical installation, wiring harness, brake configuration, and drive parameters.

Manufactured in Japan, the HG-H453BS-D48 is widely used on machining centers, CNC lathes, transfer systems, and industrial handling equipment where reliability and long service life are essential. Many maintenance teams keep this reference in spare inventory to minimize downtime and accelerate repairs in the event of unexpected motor failures.

Each motor can be tested to verify motor operation, encoder feedback, and brake functionality before shipment. Depending on availability, it may be supplied as a replacement, tested, refurbished, or exchange unit. Repair services may also be available to support older CNC systems and help extend the operational life of existing industrial equipment.

Frequently asked questions about HG-H453BS-D48:

How can I confirm compatibility with my MITSUBISHI servo amplifier?
Match the full motor code and electrical ratings to the drive’s sizing and feedback requirements, then verify connectors and brake voltage against the machine’s wiring diagram. Sharing a photo of the nameplate and the existing drive model helps our team check fit before purchase.

What does the D48 brake option indicate in practice?
It denotes an integrated holding brake variant used to secure the axis at standstill and power-off. Confirm brake characteristics with your maintenance documentation so release voltage and control wiring match your current installation.

Is this suitable as a drop-in replacement for the same code motor?
Yes, when the code matches exactly it is typically a drop-in replacement, assuming identical connectors, shaft geometry and encoder interface. Always compare the existing nameplate and connector orientation before scheduling the swap.

Can I source a refurbished or tested unit for faster turnaround?
Depending on inventory, a refurbished unit or tested unit may be available for fast dispatch. Contact us for current options, lead time and worldwide shipping arrangements.
