Executing high-performance industrial motion control requires high-accuracy equipment, and the Mitsubishi Electric HG-SR301BJK delivers this as a medium-inertia rotary servo motor optimized for the MELSERVO-J4 and MELSERVO-JE drive ecosystems. Engineered specifically with a 3.0 kW rated output and an integrated electromagnetic brake, this motor provides reliable holding torque and positional locking under heavy load states. This model features a specialized physical layout, including a keyway shaft and a built-in oil seal, allowing seamless integration into challenging mechanical setups where fluid or particulate contamination is a risk factor.

This unit directly replaces older generation HC-SFS series equivalent units, though physical dimensions and cabling pinouts differ. You must use MR-J4 series compatible cables to interface the encoder. It is ideally paired with the MR-J4-350A or MR-J4-350B servo amplifiers. Utilizing a drive rated lower than 3.5 kW will restrict performance and result in current-limit faults during peak acceleration phases.
Due to the presence of the integrated oil seal, do not operate the motor shaft without lubricant present at the seal lip. Running the oil seal dry can cause friction-induced thermal degradation of the seal material, leading to premature ingress failure. In vertical installations, ensure the brake is not being utilized to decelerate dynamic loads; the holding brake must only activate once the rotor has reached zero speed to prevent irreversible mechanical wear on the internal friction pads.
When routing cables, ensure the motor encoder feedback cable is physically segregated from the primary U/V/W motor power cable. Maintain a minimum separation distance of 100 mm inside cable carriers to prevent electromagnetic interference from triggering encoder communication faults. Utilize a surge absorber (diode) across the B1-B2 control relay contact to prevent transient voltage spikes from damaging adjacent control-system outputs.
CRITICAL WARNING:
Prior to starting mechanical or electrical installation, disconnect all incoming power supplies to the matching servo amplifier. Confirm that the charge LED on the servo amplifier has completely turned off. Wait at least 15 minutes to allow residual bus capacitor voltages to discharge below safe limits before servicing cable connections.
Mount the motor securely to a metallic machine frame configured to act as a heat sink. Ensure alignment with the load shaft to avoid excessive radial or axial force on the output shaft.
Verify that the keyway key is seated flat in the keyway slot before sliding the coupling assembly into place. Avoid hammering the shaft, as shock loads can crack the delicate internal encoder glass disk.
Route power cables (AWG 12) and brake cables (AWG 20) with strain relief to prevent pulling on the motor junction plugs.
Establish a solid low-impedance ground connection to the motor body to prevent electrostatic discharge through the shaft bearings.
