Abstract
A stator includes a stator core and a seal kit. The stator core includes a yoke part and a plurality of tooth parts. A tooth root of the tooth part is connected to the yoke part. A tooth top of the tooth part is away from the yoke part. An opening slot is formed between two adjacent tooth parts. The opening slot includes a coil slot and a flow passing slot that communicate with each other. The coil slot extends from the tooth top to the tooth root. The coil slot is configured to accommodate a stator coil. The flow passing slot extends from the tooth root to the yoke part. The seal kit is connected to an inner wall of the opening slot. The seal kit and the inner wall of the flow passing slot jointly form a flow passing passage for a coolant to flow through.
