Perma-Drive 46-3024 IP44 DC motor

The Perma‑Drive 46‑3024 is a 0.37 kW, 170 VDC permanent‑magnet DC servo motor rated at 2.7 A and 2400 rpm with IP44 protection. Common failure modes for this class include brush wear or loss of contact, winding insulation breakdown, commutator pitting, and bearing seizure due to dust ingress despite the IP44 rating. Initial diagnostics should verify that the supply voltage is within spec and that the motor controller’s drive signals are present; visually inspect brushes, commutator, and bearings for wear or contamination; and perform a continuity test of the armature windings and a resistance check between terminals to detect shorted or open coils.[oss-gpt-20b]
