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...
Answer：As the core component of modern industrial equipment, servo motors have an increasingly prominent market position. This article focuses on the overview, market size and pattern of servo motors, and the future development trends of servo motors.
Answer：variable frequency speed regulation technology has become the main speed regulation solution and can be widely used in continuously variable transmission in various industries. As frequency converters become more and more widely used in the field of ...
Answer：The inverter is a device that converts industrial frequency power ( 50Hz or 60Hz ) into AC power of various frequencies to achieve variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier...
Answer：Once the brushless DC motor is completed, the number of coils in its windings and the magnetic flux density of the permanent magnets will be determined. According to the formula, the only quantity that determines the back electromotive force is the a...
