Electric machine e.g. synchronous machine, has connection box whose one connection box cover surrounds space area of signal electronics, and another connection box cover partly surrounds space area of power electronics at housing

摘要

The machine has a connection box provided on a motor housing. The box includes a connection box lower part (50) connected with the housing, and two connection box covers (4, 5) that are screw-connected with the box lower part. Signal electronics and power electronics are provided at distance from each other in circumferential direction, arranged from salient pole rotor axis, and viewed in different angle ranges. One of the box covers surrounds space area of the signal electronics at the housing, and the other cover partly surrounds space area of the power electronics at the housing.
