Switched Reluctance Motor
Find the right devices, application kits and support to control Switched Reluctance Motors with Infineon's broad range of motor system solutions.
The Switched Reluctance Motor converts the reluctance torque into mechanical power. Power is delivered to windings in the stator rather than the rotor. When power is delivered to the stator windings, the rotor's magnetic reluctance creates a force that attempts to align the rotor with the powered windings. In order to maintain rotation, adjacent windings are powered up in turn. In modern designs a high-power electronic switching system is used, which also offers advantages in terms of control and power shaping.
- Does not utilize a permanent magnet
- Pointed poles in both stator and rotor
- Comparatively robust and efficient
- Can be used in very high ambient temperatures
- Drawbacks are acoustic noise and torque ripple
Switched reluctance motors are used in white goods as well as for example as parallel hybrid drive in hybrid vehicles as they work non dissipative and produce a higher torque.
