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.
Answer：Direct drive motor is the abbreviation of direct drive motor. It mainly refers to the motor driving the load without passing through a transmission device (such as a transmission belt, etc.). Direct drive motors are suitable for all types of washing ...
Answer：Servo motor wiring harness is specially used to connect various components in the servo system, provide power supply control for the servo motor, have excellent high-frequency response characteristics, and minimal high-frequency response heat loss, e...
Answer：To understand, we must first know what poles are: poles refer to the magnetic poles formed by the generator rotor after the excitation current is passed through the rotor coil. Simply put, it is the number of cycles of current that can be induced in...
Answer：The step angle of the motor indicates the angle that the motor rotates each time the control system sends a pulse signal. In other words, the angle that the rotor rotates each time a pulse electrical signal is input is called the step angle. It can a...
Answer：Three-phase AC servo motors are widely used, but after long-term operation, various faults will occur. Timely identification of the cause of the fault and corresponding treatment are important tasks to prevent the expansion of the fault and ensure th...
