Sensorless PMSM control for H-axis washing machine drive

摘要: In this paper a position and speed estimation method without transducer is presented. This applied for horizontal axis washing machines with permanent magnet synchronous motor (PMSM). By integrating methods, i.e. using reference zero startup low acceleration, back-EMF mid-high operation, the rotor can be estimated controlled over full range. order to achieve correct operation from speed, two techniques are combined crossover function based on reference. The proposed used in applications significant unpredictable variation loads, such as machines. Moreover, drives surface mounted PMSM or motors distorted saliency signature. To verify functionality of method, experimental validation was conducted machine.
