MITSUBISHI HG-JR103T-S121010 AC Servo motor 123V 5.6A 1kW 3000rpm

Buy online your MITSUBISHI HG-JR103T-S121010 AC Servo motor 123V 5.6A 1kW 3000rpm reference HG-JR103T-S121010 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The MITSUBISHI HG-JR series unit is a compact 1 kW AC servo motor designed for precise axis motion on CNC machines and automated equipment. In service, it works with a compatible MELSERVO amplifier to deliver closed-loop positioning, smooth speed control at 3000 rpm, and reliable torque for feed axes, indexing systems and auxiliary movements. This model is commonly sourced as a replacement motor or spare part to restore machine uptime and support retrofit projects where space and wiring constraints matter.

In a CNC control loop, the motor’s feedback communicates with the servo drive to maintain accurate interpolation and repeatable positioning over the full speed range. Its 123 V class and 5.6 A rated current suit 1 kW drive frames that see frequent start and stop operation on machining centers and turning machines. The combination of rated torque at 3.18 Nm and peak capability up to 9.55 Nm covers medium travel axes, compact rotary tables and handling fixtures that need consistent response without overshoot.

This build is supplied without a holding brake and uses a straight shaft, which makes it a solid choice for horizontal axes and mechanisms that rely on external braking or do not require static holding. Matching the complete code HG-JR103T-S121010 ensures mechanical fit, connector orientation and feedback compatibility. In many field replacements, existing power and feedback cables can be reused when the prior motor shares the same build code, which helps reduce downtime and commissioning steps.

The compact form factor of the HG-JR family supports retrofit and service replacements in tight machine bays. Typical installations include machining center X or Y feed, lathe carriage axes, gantry traverse, indexers and pick-and-place units where stable thermal behavior and repeatable accuracy are important during continuous production.

Key technical data: 1 kW rated output, base speed 3000 rpm, 123 V class, 5.6 A rated current, rated torque 3.18 Nm, maximum torque 9.55 Nm, straight shaft, no holding brake. Designed to operate in closed loop with a suitable MELSERVO servo amplifier and encoder configuration defined by the build code.

In maintenance contexts, this model is often kept as a stocked replacement unit to restore machines affected by motor faults, vibration, or bearing wear. Using the exact code simplifies drop-in replacement, helps retain existing couplings and cabling, and shortens recovery time on the production floor. It is a practical choice for preventive spares planning where a like-for-like CNC replacement component limits parameter changes.

Each motor can be tested on CNC simulators with servo drives by skilled engineers to check electrical behavior and feedback communication prior to dispatch. Units are packed with protective materials suitable for industrial transport, supplied with standard warranty, and offered with repair service, exchange service or refurbished unit options depending on availability. Shipment is typically within 3 days.

For unplanned stoppages, this item can serve as an emergency spare part to reduce downtime on legacy equipment. Cnc-shopping supports sourcing of obsolete parts and offers repair or exchange paths to keep older CNC installations running, with worldwide shipping options depending on inventory.

Frequently asked questions about HG-JR103T-S121010:

Which servo amplifier should be paired with this 1 kW motor?
Use a MELSERVO drive sized for 1 kW and compatible with the motor’s voltage class and feedback. Confirm drive capacity and parameter set against the motor nameplate and datasheet before commissioning.

Is it a drop-in for other HG-JR103T codes with different suffixes?
Match the full code HG-JR103T-S121010. Suffix details define mechanical options and feedback, so the exact reference helps ensure connector alignment, shaft interface and encoder compatibility.

Does this version include a holding brake?
No, this build is supplied without a brake. For vertical axes or applications that need static holding, select a compatible variant with a brake or use an external braking solution.

What feedback type is used on this model?
The feedback specification follows the build code. Check the motor label to identify the encoder type and adjust drive parameters accordingly to maintain closed-loop performance.

Can existing cables be reused during replacement?
If the previous motor carries the same full code and connector style, power and feedback harnesses are often reusable. Inspect connector condition and ratings before reinstallation.
