MTS 30H4-44 Servo Motor

MT30H4‑44 is a 140 VDC brushed DC servo motor rated at 3100 RPM and 19 lb‑in stall torque, commonly used in industrial motion control loops. Known failure modes for this class include brush wear or loss, commutator pitting, insulation breakdown leading to shorted windings, and overheating of the stator due to excessive current or inadequate cooling. Initial checks should verify that the power supply is delivering 140 VDC within spec, inspect the motor’s brushes and commutator for wear or damage, and review any error codes from the drive or controller for indications of over‑temperature, phase loss, or short‑to‑ground faults.[oss-gpt-20b] Post Comment
