High Speed Electric Motorcycle Manufacturers Share The Operating Structure Of Switched Reluctance Motors
High Speed Electric Motorcycle manufacturers share the advantages of switched reluctance motors are:
1. The magnetoresistive electric vehicle motor has a simple structure and low cost. The structure of the switched reluctance motor is simpler than usual. Its outstanding advantage is that there is no winding of any kind on the rotor, so there will be no problems such as poor casting of the squirrel cage and broken bars in use during the manufacturing process of the squirrel cage induction motor. The rotor has extremely high mechanical strength and can be used for ultra-high speed operation. In terms of the stator, it has only a few concentrated windings, so it is easy to manufacture and easy to insulate.
2. The power circuit is simple and reliable. Because the direction of motor torque is independent of the direction of winding current, that is, only one direction of winding current is required, so the power circuit can achieve one power switch per phase, and each power switch element is directly connected in series with the motor winding, which fundamentally avoids Straight-through short-circuit phenomenon. Therefore, the protection circuit of the power circuit in the speed control system of the switched reluctance motor can be simplified, which not only reduces the cost but also improves the working reliability.
3. Each phase can work independently with high reliability. From the perspective of the electromagnetic structure of the motor, each phase winding and the magnetic circuit are independent of each other, and each generates electromagnetic torque within a certain axis angle, unlike the general motor that must produce a rotation under the joint action of each phase winding and the magnetic circuit. The magnetic field can make the electric car motor work normally. From the point of view of the controller structure, the power supply of each phase circuit to one phase winding generally works independently from each other. It can be seen from this that when the motor one-phase winding or the controller one-phase circuit applauds, it is only necessary to stop the operation of the phase, and the motor has no other problem except that the total output power capacity is reduced. Therefore, the system has extremely high reliability and can be used in aerospace, electric vehicles, etc.
4. The starting current is small and the torque is large. The low starting current controller absorbs less current from the power supply side and obtains a larger starting torque on the motor side is a major feature of the reluctance motor. Therefore, the switched reluctance motor is very suitable for electric vehicles and other machines that require heavy-duty starting and long-term low-speed heavy-duty operation.
