Magnetic Design of a Switched Reluctance Motor for Electric Power Tools

This paper describes the design of a switched reluctance motor for portable power tools by means of numerical field calculations. The motor was designed for a nominal speed range from 7,500 rpm to 15,000 rpm and a rated torque of 2.25 Nm. The rated output power of the motor is 2,945 W, thus 2,700 W...

Summary:This paper describes the design of a switched reluctance motor for portable power tools by means of numerical field calculations. The motor was designed for a nominal speed range from 7,500 rpm to 15,000 rpm and a rated torque of 2.25 Nm. The rated output power of the motor is 2,945 W, thus 2,700 W are available after the gears in continuous operation. Motor speed and gear ratios are adjustable. The drive concept has already been successfully used in a serial production of core drill machines.
