Answer：The motor is a component that converts battery electrical energy into mechanical energy and drives the wheels of an electric vehicle to rotate.
Answer：A permanent magnet (PM) motor is an AC motor that uses magnets embedded or attached to the surface of the motor rotor. Electric vehicles use permanent magnet synchronous motors with high torque density and high efficiency. The magnets used are neodym...
Answer：The high-end development of new energy vehicles, the pursuit of stronger power, put forward higher requirements for acceleration from 100 kilometers. In particular, some high-end models are selling well, and the power index has become the focus of co...
Answer：The stepper motor is an open-loop control element stepper motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequenc...
Answer：The use of permanent magnet motors in combination with variable frequency drives is not new, and design engineers and equipment owners are beginning to choose more permanent magnet motor solutions for fan and pump application installations because th...
Answer：Motor type, soft start method, selection steps, damage causes and treatment methods, the difference between good and bad motors... All these problems are important reflections of the motor happiness index.
Answer：Switched reluctance motor ( SR for short ) was born 160 years ago, but it has been considered as a motor with low performance for a long period of time, so it is only used in a few small power places. In the early 1970s, Ford Motor Company of the Uni...
Answer：China's automotive motors have obvious comparative advantages under global resource conditions and have great development potential. From the perspective of the industry chain of new energy vehicles, the beneficiaries will mainly focus on the co...
Answer：Hub motor technology, also known as wheel built-in motor technology, is a hub device technology that integrates the motor, transmission system and braking system. The layout of the drive system using this technology is very flexible, allowing electri...
Answer：The metal shell of the motor is mainly made of cast iron, steel plate and aluminum. With the pursuit of the appearance and beauty of the motor, the aluminum shell motor is continuously recognized by the market, but as a motorist, we are very clear ab...
