STATOR WINDING PATTERN FOR HAIRPIN DRIVE MOTOR |
摘要 |
A stator winding pattern of a hairpin drive motor includes a stator with 8 poles and 48 slots of a distribution winding where a hairpin-type of flat coil is inserted into a slot of a stator core and configured by a full pitch winding implementing 6 pitches of 3 phases and 2 in parallel, the pitch being a distance between adjacent slots, characterized in that: first to fourth layers are formed in the slot of the stator core in a radial direction of the stator core; and when a first layer or a fourth layer is set as a draw out part of one phase in an optional reference slot, a first draw out of a different phase is formed in a draw out slot having 16 pitches in a slot forward direction in a same layer based on the reference slot, and a second draw out of the different phase is formed in a draw out slot having 32 pitches in the slot forward direction in the same layer based on the reference slot. |

1. A stator winding pattern of a hairpin drive motor including a stator with 8 poles and 48 slots of a distribution winding where a hairpin-type of flat coil is inserted into a slot of a stator core and configured by a full pitch winding implementing 6 pitches of 3 phases and 2 in parallel, the pitch being a distance between adjacent slots, characterized in that:
first to fourth layers are formed in the slot of the stator core in a radial direction of the stator core; and when a first layer or a fourth layer is set as a draw out part of one phase in an optional reference slot, a first draw out of a different phase is formed in a draw out slot having 16 pitches in a slot forward direction in a same layer based on the reference slot, and a second draw out of the different phase is formed in a draw out slot having 32 pitches in the slot forward direction in the same layer based on the reference slot. |
