A high speed linear motor excited synchronous multiphase

The present invention belongs to the field of linear motors, particularly relates to a high-speed multiphase electrically excited synchronous linear motors. The linear motor of the present invention, the bottom of the bottom chassis fixed to the carriage, the carriage is provided chute bottom; top chassis disposed support panel, the bottom ends mover disposed bottom slider body, a shoulder is provided at the top mover slider body ; movable sub-coil tip connecting the brush mover; bottom powered rails disposed on both sides of the carriage, the mover and the power supply rail slidably connected to the brush; motor stator fixed on the frame; mover towing hook body top surface is provided. The linear motor of the present invention, the mover using the excitation power supply rail, the movable sub-coil using a hollow coreless coil, the mover body made of plastic, so that a smaller portion of the entire mass of the motor mover, easy to control. The stator adopts bilateral structure, run more smoothly. Motor with coil excitation, simply adjust the excitation voltage and the current is easy to adjust the operating state of the motor, the control is more convenient and flexible.
