Electric Vehicles and the Revolution of BLDC/PMSM Motors
Electric Vehicles (EVs) are not just a trend; they are a significant step towards a sustainable future. With a sharp rise in awareness about environmental issues, the shift from internal combustion engines to electric motors has become inevitable. Among the various electric motor technologies, Brushless DC Motors (BLDC) and Permanent Magnet Synchronous Motors (PMSM) are the key drivers in the field of EVs. Here’s why: Brushless DC Motors (BLDC) in EVs BLDC motors are highly efficient and offer a good torque-to-weight ratio, making them increasingly popular in EVs. 1. Construction & Working: - Stator : Wound with three-phase windings, it creates a rotating magnetic field. - Rotor : Contains permanent magnets and rotates in response to the magnetic field generated by the stator. - Electronic Controller : Controls the current and voltage supplied to the stator. 2. Advantages: - Efficiency : BLDC motors are about 90% efficient, transla...
