NO >> Replace the traction motor. Refer to TMS-109, "Removal and Installation" Component Inspection (Traction Motor Stator Coil) INFOID:0000000010120992 1. CHECK RESISTANCE OF TRACTION MOTOR STATOR COIL Using a milliohmmeter and check the resistance traction motor stator coil. CAUTION: As resistance of stator coil is affected by temperature, check it at least 8 hour after removal of service plug. *: The value is at 20 °C (68°F). Calculate the resistance standard value based on actual ambient temperature at operation based on the below calculation formula. Calculating formula • R20=R/[1+ 0.00393 × (T−20)] - R20: Resistance value (m Ω) at 20°C (68°F) - R: Resistance value (m Ω) at actual ambient temperature at operation - T: Actual ambient temperature [ °C (°F)] at operation Is the inspection result normal? YES >> INSPECTION END NO >> Replace the traction motor due to malfunction in the stator coil.
