Abstract

The invention provides a driving and motor integration machine for a wind power generation variable propeller system. The driving and motor integration machine comprises a driving portion and a motorportion. The driving portion and the motor portion are connected with each other. A driving circuit, a switch power source and a control circuit are integrated on the driving portion. A permanent magnet synchronous motor, a motor brake, a position / speed sensor and a KTY temperature sensor are integrated on the motor portion. The driving signal output end of the control circuit is connected to thedriving signal input end of the driving circuit, and the driving signal output end of the driving circuit is connected to the driving signal input end of the permanent magnet synchronous motor. The motor brake is connected to a brake interface of the control circuit, the speed sensor is connected to an encoder interface of the control circuit, and the KTY temperature sensor is connected to a temperature sensor interface of the control circuit.

Description

technical field [0001] The invention belongs to the technical field of servo drives, and in particular relates to a drive-motor integrated machine for a wind power generation pitch system. Background technique [0002] The pitch control system is an important device for the control and protection of wind turbines above MW level, and it is the main braking system for the wind turbine to stop, which is crucial to the operation safety of the whole machine. Although the pitch control system accounts for a small proportion of the overall machine investment, the subsequent operation and maintenance costs account for a relatively high proportion. Therefore, with the renewal and development of wind power market technology in the past ten years, the requirements for reducing the failure rate of the pitch control system and improving its operational reliability are becoming more and more urgent. [0003] The servo driver and motor of the existing wind turbine pitch system are set sep...
