Abstract
The utility model relates to electromagnetic ejection technical field especially relates to a moving coil type electromagnetic ejection device, including ejection mounting seat, magnetic nonuniform stator subassembly, current rail, power supply subassembly and linear motor motor subassembly, magnetic nonuniform stator subassembly and current rail all are along first direction and set up on ejection mounting seat, and magnetic nonuniform stator subassembly and current rail interval setting, magnetic nonuniform stator subassembly can produce nonuniform magnetic field, power supply subassembly and current rail electricity are connected, can power supply for current rail, linear motor motor subassembly sliding sets up on current rail, under the action of nonuniform magnetic field linear motor motor subassembly can along current rail and carry out acceleration motion and deceleration motion. The utility model does not need external frequency converter to match the thrust demand of different speed section, has reduced system complexity, and magnetic field distribution matches the ejection curve, avoids the thrust pulsation caused by uniform stator in prior art, reduces invalid energy consumption.
