Generating torque in starting of self-controlled synchronous motor is analyzed, and the developed method of torque measurement using the space rotating current vector is described. A self-controlled synchronous motor known as a commutatorless dc motor, consists of a synchronous motor with a shaft position sensor and a inverter switched by the pulses from the position sensor. The inverter frequency...
This paper deals with the realization technique that optimizes the flux level to improve the efficiency of an induction motor. When harmonics and saturation effects are considered, the slip of minimum loss, or optimal slip, depends both on the speed and on the load torque. The measurements of speed and torque are achieved with motor terminal quantities dispensing with conventional torque and speed...
The goal of the field orientated control principle for inverter fed asynchronous machines, is to control the torque of the machine and the flux inside the machine independently from each other.
