Product Description
The Mitsubishi HG-KN73B is a 0.75 kW brushless servo motor with a 3000 RPM rated speed (5000 RPM max), 2.4 Nm rated torque (7.2 Nm max), and IP65-rated protection, designed for efficient, precise, and safe operation in small-capacity industrial applications due to its low inertia, electromagnetic brake, natural cooling, and straightforward installation via a straight shaft.
Is Your Device Showing These Signs?
The Mitsubishi HG-KN73B AC servo motor commonly requires repair due to encoder failures, resulting in positioning errors and drive faults. Overheating from excessive load or inadequate cooling damages windings, causing insulation breakdown and short circuits. Bearing wear leads to increased friction, audible noise, and eventual motor seizure. Connector damage and cable degradation interrupt signal transmission, triggering communication errors with the servo amplifier. Resolving these issues involves encoder replacement, motor rewinding, bearing replacement, and cable/connector repair to restore optimal performance.

Our Repair Process for the
HG-KN73B
Our repair process for the Mitsubishi HG-KN73B AC servo motor begins with a comprehensive diagnostic assessment to pinpoint the failure's root cause, whether it stems from encoder malfunction, winding damage due to overheating, bearing wear, or connector/cable issues. Encoder failures necessitate complete replacement with a new, calibrated unit to eliminate positioning errors. Overheated windings require professional rewinding using high-quality insulation materials to prevent future short circuits. Bearing wear is addressed through complete bearing replacement, reducing friction and noise, and preventing motor seizure. Damaged connectors and degraded cables are repaired or replaced to ensure uninterrupted signal transmission and eliminate communication errors with the servo amplifier. Each repair concludes with rigorous testing under load to guarantee the motor meets original performance specifications, ensuring reliable operation upon reinstallation.
