MITSUBISHI HG-H453BS AC Servo Motor 3500rpm 4.5kW Brake - NO Encoder

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

The MITSUBISHI HG-H453BS is an industrial AC servo motor from the HG series designed for CNC axis control and demanding motion applications. Rated in the 4.5 kW class, this motor features an integrated holding brake and is supplied without an encoder, making it a practical solution for maintenance projects where the original feedback device can be reused or a compatible encoder is installed separately.

Designed for use with compatible MITSUBISHI MELSERVO servo amplifiers, the HG-H453BS provides reliable torque delivery, accurate positioning, and smooth motion control for machine tool feed axes and automation equipment. The integrated brake is particularly beneficial on vertical axes and load-holding applications, helping to maintain position safely during power loss, emergency stops, or maintenance procedures.

This motor is commonly installed on machining centers, CNC lathes, gantry systems, indexing tables, rotary fixtures, and industrial handling equipment where repeatable positioning and high-duty performance are required. Its 176 mm square flange and straight shaft design make it suitable for like-for-like replacement projects when mechanical and electrical specifications match the original installation.

Because the unit is supplied without an encoder, proper integration requires selecting or reusing a feedback device compatible with both the motor and the target MELSERVO drive. Correct amplifier sizing, encoder compatibility, and parameter configuration are essential to ensure stable operation, accurate commutation, and optimal servo tuning.

Manufactured in Japan, the HG-H453BS is frequently sourced as a replacement motor for systems experiencing winding faults, bearing wear, brake degradation, or general performance deterioration. Many maintenance departments keep this reference in spare inventory to minimize repair times and reduce unplanned production downtime. Prior to installation, technicians should verify flange dimensions, shaft configuration, connector orientation, and encoder interface compatibility to ensure a seamless replacement.

Each motor can be tested on dedicated servo benches and CNC simulation equipment, including insulation verification, phase balance checks, brake functionality testing, and operational run tests with a matched servo amplifier. Depending on availability, the motor may be supplied as a replacement, tested, or refurbished unit. Repair and exchange services can also be provided to support legacy CNC and automation systems, helping manufacturers maintain equipment availability while avoiding costly machine upgrades.

Frequently asked questions about HG-H453BS:

Does this motor include an encoder?
No, it is supplied without encoder. You can reuse the existing encoder if compatible or install a Mitsubishi approved feedback unit matched to the amplifier and application.

Is the holding brake included and what is its role?
Yes, a holding brake is integrated. It secures the axis at standstill and during power off, which is especially useful on vertical axes and fixtures that must not drift.

Which drives are compatible with this model?
It is intended for use with MELSERVO amplifiers that support HG series motors of the same power class and encoder specification. Verify drive matching, encoder type and brake control against the motor nameplate and machine documentation.

Can this be used as a drop in replacement for an existing HG motor?
Often yes when the mechanical interface and electrical parameters match the original. Check frame size, flange, shaft, connectors, encoder interface and brake wiring before field replacement.

Do you support repair or exchange options?
Cnc-shopping can provide repair service, exchange service and refurbished unit options depending on evaluation and inventory. This helps reduce downtime while maintaining machine uptime with a tested unit.
