Answer：A three-phase motor means that when the three-phase stator winding of the motor (each phase differs by 120 degrees electrical angle) is supplied with three-phase alternating current, a rotating magnetic field will be generated. This rotating magnetic...
Answer：There are two most common reasons for motor burnout, with phase loss and bearing damage being the most common.
Answer：Traditionally, there are two directions in motor design: copper motor and iron motor. Copper motor uses electric field as the main source of motor torque, which involves the current (I) and the number of enameled coils (N) in the motor torque formula...
Answer：Industrial-grade motors are quite durable. As long as a motor is not overloaded, it can work stably for more than ten years without any pressure. Today, we will introduce the guarantees behind the motor's ultra-long battery life.
Answer：When we incorporate servo motors into new machine designs, we often face various challenges: for example, under what circumstances would a frameless motor be a better choice than a traditional framed motor. To answer this question, we need to first u...
Answer：After replacing with a high-efficiency motor, the current will be too high during the total operation. Therefore, all motors need to be replaced, and the power consumption will also increase. This article will analyze the reasons for the high current...
Answer：While the motor converts electrical energy into mechanical energy, it also loses some energy. Motor losses can generally be divided into three parts: variable losses, fixed losses and stray losses .
Answer：BLDC (Brushless DC Motor) and DD (Direct Drive Motor) are two different types of motors that differ in design, working principle, performance, and application areas. This article will introduce in detail the characteristics, advantages and disadvanta...
Answer：The weak magnetic field function of the motor means that during the motor startup process, the motor control system will first apply a small current to the motor to make the motor rotor generate a certain degree of magnetic field, but it is not enoug...
Answer：There are three main excitation methods for DC motors: separate excitation, parallel excitation and series excitation. The following will introduce the characteristics and applications of these three excitation methods in detail.
