Renesas Electronics Corporation has introduced the RA2T1 microcontroller group based on the Arm Cortex-M23 processor, ...

Rotation speeds of a motor 3 mm in diameter have been characterized up to 2000 r/min as a function of voltage, phase, and frequency, with power consumption less than 4 mW. Frequency characterization ...

In this paper, an adaptation of a shaded pole motor operating as a single-phase brushless PM motor is studied. After properly designing the rotor PM ring to avoid demagnetization problems, a nonlinear ...
