MITSUBISHI HC53S-SZ AC Servo Motor 127V 3.2A 3000rpm 0.5kW + OSA104S2 Encoder

Buy online your MITSUBISHI HC53S-SZ AC Servo Motor from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The HC53S-SZ from Mitsubishi Electric is a compact AC servo motor designed for closed-loop axis control in CNC machine tools and industrial automation systems. Rated at 0.5 kW with a base speed of 3000 rpm, it delivers accurate positioning and reliable speed regulation through its integrated OSA104S2 encoder.

Part of the HC53S-SZ series, this servo motor is engineered to provide stable torque throughout its operating range while maintaining precise position feedback. Its 127 V operating class and 3.2 A current rating make it compatible with Mitsubishi servo drives of the same generation, providing a practical replacement solution for existing motion control systems.

The motor is commonly installed on feed axes of compact machining centers, CNC lathes, automatic loading systems, and positioning fixtures requiring precise linear or rotary motion. The integrated OSA104S2 encoder enables accurate closed-loop control, allowing the drive to maintain precise speed and position during rapid traverses, interpolation, and high-precision machining operations.

Matching the complete HC53S-SZ part number is essential to ensure compatibility with the existing mechanical mounting, electrical connections, and encoder interface. Using the correct replacement motor typically allows a direct installation without major wiring modifications or extensive drive reconfiguration, helping reduce commissioning time and machine downtime.

Manufactured in Japan, this servo motor is widely used for maintenance, retrofit, and repair of legacy Mitsubishi CNC and automation systems. It is frequently selected to replace failed motors, resolve following errors, restore stable homing performance, and eliminate axis alarms while extending the service life of existing equipment.

Thanks to its robust construction, integrated feedback system, and compatibility with Mitsubishi motion control platforms, the HC53S-SZ is a dependable replacement solution for maintenance teams seeking to minimize downtime and preserve the long-term performance of CNC machinery and industrial automation equipment.

Frequently asked questions about HC53S-SZ:

Is this a direct field replacement for an installed HC53S-SZ with an OSA104S2 feedback device
Yes, it is intended as a like-for-like swap when the original carries the same model and encoder designation. Always confirm the nameplate data and connector orientation against the installed unit.

What feedback interface does the OSA104S2 provide
The OSA104S2 is a recognized encoder type used with matching MITSUBISHI drive inputs. It provides high-resolution position and speed feedback required for closed-loop axis control on compatible amplifiers from the same generation.

What electrical ratings should the drive support
The motor is rated 127 V class with a 3.2 A current rating and 0.5 kW at 3000 rpm. The drive should match these ratings and accept the OSA104S2 feedback format.

Where is this motor typically used in CNC applications
It commonly runs X, Y, or Z feed axes on compact machine tools, and can also serve positioning roles on loaders or fixtures where accurate motion and repeatable homing are required.

Can you help if my original unit is no longer available new
Yes, we can support sourcing of obsolete or refurbished units and provide repair or exchange options to keep your machine running with minimal downtime.
