Abstract

Most modern commercial electric scooters are still equipped with the DC brush motor. This type of motor has mechanical structures such as permanent magnet, brush, and commutator. Therefore, it has attractive features, e.g., large start-up torque and easy to control. However, this kind of mechanical commutation often leads to drawbacks such as low power density, low reliability, and poor heat dissipation. In contrast, the Permanent Magnet Brushless Motors (PMBLMs) have advantages such as high efficiency and maintenance free, etc. Hence, the PMBLMs have great potential in becoming the actuators for electric scooters. In this paper, the performance of the PMBLMs with trapezoidal and sinusoidal back-emf waveforms driven by square wave commutation and sinusoidal commutation is investigated. To reduce the cost, low-resolution Hall sensors are used to implement sinusoidal commutation.
