Answer：When the voltage is reduced, the motor, as the core device of electric drive, will experience a series of significant changes. The following is a detailed analysis of these changes to help better understand the impact of voltage reduction on motor pe...
Answer：Reasons why the single-phase motor does not rotate and hums: (1) Single-phase operation due to power connection problems: (2) The motor is overloaded; (3) Stuck by the towing machinery; (4) The rotor circuit of the wound-rotor motor is open and disco...
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...
