- Q: Is there a sensor in the electric forklift motor? If there is a failure, can the car still walk?
- Electric forklift truck technology has experienced from ac to dc, and returned to the change of communication, the earliest communication technology because of restricted by technology and electronic parts so no, later is popular, dc technology with ac motor, ac electric control, the development of the contactor gradually eliminate dc technology. The dc motor has a carbon brush, which is time-consuming and time-consuming to maintain, and because of the technical constraints, it is often the phenomenon of burning the electrical parts. And the communication technology has greatly improved the service life of the parts of the forklift truck, and the motor has no brush motor
- Q: Is the brushless dc motor a synchronous motor or asynchronous machine? Thank you very much!
- The principle of brushless dc motor is different from that of ordinary induction motor, which cannot be separated by synchronous or asynchronous. The so-called synchronous and asynchronous means that the rotor and air gap in the rotor and air gap hold the same rotational speed while the motor is running.
- Q: Is a single-phase carbon brush motor a dc motor or ac motor?
- use Synchronous motors are used mostly in large generators, while asynchronous motors are used almost exclusively in motor situations. The synchronous motor can adjust the power factor by the excitation. The power factor of asynchronous motor is adjustable, so in some large factories, application of asynchronous motor is large, can be added a synchronous motor for condenser, used to adjust the plant and the power factor of power network interface. However, due to the synchronous motor of high cost, maintenance workload is big, now commonly used capacitance compensation power factor. Synchronous machine with exciting winding and the slip ring, need the operator had a higher level to control excitation, in addition, compared with those of asynchronous machine maintenance free maintenance workload is bigger; So, as an electric motor, most current asynchronous motors are chosen.
- Q: What is excitation, excitation current, what is the difference between motor and generator
- The excitation current is provided by the independent power supply for the motor excitation winding. For example, the use of an independent dc power source for the excitation winding of a dc generator; The electromagnetic field of the armature winding of the asynchronous motor is generated by ac power supply. The former is the dc excitation, the latter is the exchange excitation. Synchronous motor according to the situation of the power grid, can be a rotor field winding dc excitation, can also be provided by the grid ac excitation on the stator, the general is given priority to with dc excitation. If the dc excitation is insufficient, then the reactive reactive current from the grid input is added to the motor. If the dc excitation method is overused, the motor will output the backward reactive current to the grid, weakening the internal magnetic field of the motor. When the dc excitation is adopted, the voltage drop in the excitation circuit is only caused by the resistance, the excitation voltage is low, and the excitation power supply is small. With the use of ac excitation, the excitation voltage is much higher, and the capacity of excitation power supply is much higher.
- Q: Which is better for dc speed regulating motor and ac converter?
- See how big power, want to achieve what effect, small power, dc speed regulation general cheaper a few, big power estimate is ac electric machine. The structure of dc speed regulating system is complicated, the maintenance cost is high, the dc motor structure is more complicated than the ac, and the price is high. Inverter easy to use, the price is not expensive, cheaper ac motor, frequency converter and PLC is widely used in many fields. But not necessarily must use ac speed regulating motor. On the upfront costs, general inverter about price range in 700-3000. Dc speed governor is a kind of motor speed control device, including dc motor speed, pulse width, dc speed regulator, SCR dc speed regulator, etc., generally for modular dc motor speed regulator, integrating the power, control, drive circuit, using three-dimensional structure layout, control circuit adopts micro power components. Frequency conversion motor adopts "special inverter induction motor + frequency converter" way of ac speed regulation, make the mechanical automation degree and greatly improved the efficiency of production equipment miniaturization, increase comfort, is to replace the traditional mechanical control and dc speed control scheme
- Q: Why is dc motor less efficient than ac motor
- As the name suggests, dc motors use direct current as a power source. Ac motor is used as an ac power supply. According to the structure, the principle of dc motor is relatively simple, but the structure is complex and not easy to maintain.
- Q: The difference between dc brushless motor and ac servo motor
- Simple dc brushless motor can not do position control and can only do speed control. Ac servo can do position control and other kinds of control.
- Q: Question about the general motors?
- Naturally, it's alternating current and dc, so it's not positive, because the communication is positive and negative
- Q: 380v's ac motor operates under 330v voltage
- It is normal to be able to be driven, the difference is a few dozen volts different, it is only to calculate to be able to discover, the surface is not visible to the naked eye.
- Q: Do you start the coils when you are communicating?
- There are many kinds of single phase ac motor, such as capacitance shingles, resistors, electric motors, and "swinging" motors.
