COIL FOR LOW-VOLTAGE INVERTER DRIVE MOTOR

摘要

The present invention provides a coil for a low-voltage inverter drive motor having insulation performance preventing the insulation breakdown even when partial discharge occurs within the warranty period of the motor. The coil is used for a low-voltage inverter drive motor that is driven at a low voltage of less than AC 700 V by an inverter power supply, the coil is formed of an insulated wire, and a total discharged charge amount discharged until an expiration of the warranty period is less than 10 C/mm2. The insulated wire is provided with a conductive wire and an insulation coating layer, the insulation coating layer being disposed covering the periphery of the conductive wire.
