- Q:What subjects should be included in the purchase of ac contacts and motors?
- Buy two should belong to the ac contactor and motor parts, are not used alone, should it be used to repair the equipment, so directly into the cost - during repairs. For continuous, systematic and comprehensive accounting and supervision of economic activity caused by the change of accounting elements, it is necessary for the specific content of accounting object according to the different characteristics and economic management requirements for scientific classification, and determine the classification of accounting project name in advance, provisions of the accounting content. The program that classifies the specific content of an accounting element is called an accounting subject
- Q:What will be the result of the power supply to ac motor after the rectifier (not filtering)?
- The motor doesn't turn, it's hot, it's oscillating,However, dc motors can be turned. Because the current flowing in one direction is in the same direction as the direct current.
- Q:Control the power ac motor with thyristor or relay?
- Direct starting? Pay more attention on get a molded case circuit breaker with motor protection remote control words that do with contactor control circuit breaker short circuit protection Although a bit bad Make the correct choice is capacity
- Q:Can alternator speed improve power generation?
- You say the speed is less than 3,000, the torque of the rotor is not rotating, the motor is taking energy from the grid and keeping it constant, It doesn't provide energy to the grid. Rotor torque, the generator can generate electricity is the fundamental condition, the rotor can rotate, because the rotor torque, such as water can hydraulic generators, wind generators, etc.
- Q:How does the three-phase alternator work?
- The three-phase alternator is usually made up of stator, rotor, end cover, brush, seat and bearing. The stator is composed of the machine seat. Stator iron core, wire wrap winding, and other structural parts that are fixed in these parts. The rotor is made up of rotor core, rotor magnet (magnetic coil), slide ring, (also known as brass ring), fan and shaft.
- Q:How does ac motor speed control
- There are three kinds of speed regulating methods One is to use a transducer to change the frequency of the power supply. The second is to change the extreme number of the motor (the requirement for the motor). Three is the slide differential governor. This doesn't actually change the motor speed. It is the variation of the differential clutch that is connected to the motor shaft, changing the speed of the clutch output shaft.
- Q:60W regular ac motor needs to be fast and slow before stopping, how to control?
- You want to know how fast you're talking, how long does it take to stop the process and how long does it take to complete the process?
- Q:The type of speed adjustment of ac motor and the difference between them
- Variable frequency adjustable speed -- -- -- -- - this is by far the most common way of speed regulation, can achieve stepless speed regulation, after semiconductor converter circuit (or) change the frequency of the motor power supply, the mains frequency (= 50 hz) change as needed to achieve the purpose of speed regulation, frequency or the above formula: ac motor synchronous speed = 60 f/pole logarithm, th
- Q:Is the servo motor a dc motor or ac motor?
- What is a step motor? A step motor is an actuator that converts electrical impulses into angular displacement. Popular point: when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (and the step Angle). You can control the amount of angular displacement by controlling the number of pulses, so that the target is accurate. At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency. There are three types of steps: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 15 degrees. The reaction type step is generally three-phase, can realize the big torque output, the step Angle usually is 1.5 degrees, but the noise and vibration are very large. Developed countries such as the United States and Europe were eliminated in the 1980s. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phases and five phases: the Angle of two phases is 1.8 degrees and the Angle is 0.72 degrees. This step is the most widely used.
- Q:The motor in the hair dryer is ac motor, or dc motor
- If an electric blower is connected to a 220V power supply, it is the ac motor.
