Permanently-actuated electrical synchronous machine e.g. marine drive machine, controlling method, involves using specific torque compensation value for consideration of specified temperature dependence of magnetic flux

摘要

The method involves producing a torque by a machine current and a magnetic flux which is produced by permanent magnets. The torque depends upon the strength of the magnetic flux, measurement of the machine current and a machine constant. The machine current and the torque of the machine are regulated. A specific torque compensation value is used for the consideration of the specified temperature dependence of the magnetic flux. Independent claims are also included for the following: (A) a device for implementing a method of regulation of a permanently-actuated electrical synchronous machine; and (B) an application of a device for controlling a rudder propeller engine.
