When the three-phase stator windings of the permanent magnet motor (each with a phase difference of 120 u0026 deg; TV points) are fed with three-phase alternating current with a frequency of f, a rotating magnetic field will occur at a synchronous speed. In the steady state, the main pole magnetic field rolls synchronously with the […]

Successfully won the bid for the procurement of three 400 MW units and their auxiliary equipment of the Yangjiang Pumped Storage Power Station in Guangdong, which is currently the largest single-meter 700-meter high-head pumped storage project in China. All units of the power station will be manufactured by Harbin Electric. Pumped storage power station is […]

Stepper motor is a kind of discrete motion equipment, which has substantial connection with modern digital control technology. In the current domestic digital control system, the use of stepper motors is very extensive. With the appearance of the all-digital AC servo system, AC servo motors are increasingly used in digital control systems. In order to […]

Geared motors are currently used in the addition and subtraction of various general mechanical equipment in the steel and machinery industries. There are many types of geared motors. To classify them, they can be roughly divided into high power geared motors, coaxial helical geared motors, parallel shaft helical geared motors, spiral bevel geared motors, and […]

As we all know, the servo of the servo motor is composed of three feedback systems: the azimuth loop, the speed loop, and the current loop. The more internal the loop, the more it needs to improve its responsivity. Failure to comply with this criterion will cause errors and vibration. Since the current loop is […]

High-voltage motors are an important device for machinery and other occupations. When high-voltage motors have problems, we need to Range hood motor manufacturers repair them in a timely manner. Here, we should have certain knowledge: if high-voltage motors have problems, we cannot solve them ourselves. Find relevant professionals for inspection and repair. Because repair of high-voltage […]

Regarding three-phase motors, the stator winding has two types of connection: triangle and star. The star connection is to connect the tails of the three-phase windings together, and the head of the three-phase windings is connected to the power supply. The star connection has external star connection and internal connection. There are two conditions for […]

Stepping motors and servo motors have always been our target of comparison. Today, the editor of the day told us how the control accuracy of stepper motors and servo integrated stove motor suppliers motors differ. 1. The force, torque, speed and Talent of other factors: Compared with the open-loop system, the servo control system has fewer […]

Introduction In the study of the temperature characteristics of thermal convection acceleration sensors, the sensor system needs to be placed on a rotating table that can be rotated 360 degrees in the longitudinal direction, and the rotating table should be placed in a constant temperature test chamber. When the rotary table rotates, the phenomenon that […]
