What is a power frequency motor?_Power frequency motor to variable frequency motor What is a power frequency motor? Synchronous motor refers to an AC motor that is directly driven by the utility power supply (usually 50Hz or 60Hz) as the power source, they are often used in some low-precision, low-speed, low-demand applications. The advantages of synchronous motors are simple structure, high reliability, and low cost, but the disadvantages are that the speed and torque are difficult to control and regulate, the precision is low, and they are not suitable for high-precision control requirements. In modern industrial production, with the increasing demand for product quality and efficiency, more and more applications require higher precision and control performance, thus frequency conversion motors gradually replace AC motors and become the mainstream. Frequency conversion motors can control the speed and torque of the motor through frequency converters, improve the efficiency and precision of the motor, and are suitable for a wider range of application fields.
