Motor and gas turbine including same

Abstract

A motor includes a stator, a rotor and a motor base. The stator includes a stator core and a stator winding wound on the stator core. The rotor includes a magnet which is mounted on a motor shaft andcan rotate with the motor shaft. The stator is fixedly supported on the motor base, and the motor shaft is rotationally supported on the motor base through at least one bearing. The rotor is located near one end of the motor shaft, the at least one bearing is arranged near the other end of the motor shaft opposite to the rotor, and the rotor is in a cantilever structure. The motor has a simple andcompact structure, and is convenient to maintain. A gas turbine including the motor is further disclosed.

Description

technical field [0001] The present invention relates to an electrical machine that can be used in various mechanical equipment, for example as a generator for a gas turbine. The invention also relates to a gas turbine comprising such an electrical machine. Background technique [0002] A motor is a device that can convert electrical energy into mechanical energy or convert mechanical energy into electrical energy. It is widely used in various fields and is used as a power source for many machines. In a powered machine such as a gas turbine, there is usually an electric motor for its initial start-up. [0003] figure 1 A schematic diagram of the construction principle of a conventional gas turbine with an electric motor is shown. Wherein, the main part of the gas turbine 1 includes a compressor 10 , a turbine 20 and a combustion chamber 30 , and the compressor wheel of the compressor 10 and the turbine wheel of the turbine 20 are connected by a shaft 40 . During operation...
