Answer：Low-speed electric four-wheelers, three-wheelers and electric trucks on the market today mainly have two drive systems, AC systems and DC permanent magnet systems.
Answer：The oil replenishment and oil change of the motor bearings should be handled correctly according to the on-site usage conditions. It is not static, and problems must be checked frequently and dealt with promptly to keep the motor in good operating co...
Answer：The explosive growth of the new energy motor and electronic control industry began in 2016. As the main components of new energy vehicles, motors and electronic controls account for approximately 10% and 11% of the total vehicle cost, and their marke...
Answer：Please note that before performing any repair operations, you should ensure that the motor is turned off and the power source is disconnected to avoid the risk of electric shock. In addition, if you are not familiar with micro motor repair operations...
Answer：The position sensor is one of the components of the brushless DC motor system. Its function is to detect the relative position of the main rotor to the stator winding during movement, convert the position signal of the permanent magnet rotor magnetic...
Answer：Due to the weak research foundation, the industrialization level of high-speed motors in China is low, and there is still a large gap compared with foreign countries. In particular, high-power high-speed motors above the megawatt level and ultra-high...
Answer：Small motors break through the traditional concept of electromagnetic motors. Small motors have no magnetic field windings and magnetic circuits, and do not rely on electromagnetic induction interaction to convert energy. Instead, they only use the i...
Answer：motor shaft breakage may be caused by various reasons such as overload, unbalanced load, shaft material problems, bearing failure, design or manufacturing defects, vibration and shock, temperature problems, and improper maintenance. Through measures ...
Answer：Insulation overlap is when the slot insulation and end insulation of the coil stator coil are wrapped with two materials. The two materials should be overlapped at a certain position, that is, insulation overlap. The insulation overlap and winding ar...
Answer：Switched reluctance motors and synchronous reluctance motors are both high-efficiency and energy-saving motors and are widely used. They can also be used for energy-saving upgrades of old asynchronous motors, which can significantly reduce power cons...
