Q:The difference between high voltage motor and general motors
Main is the grade of power supply voltage is different, the factory high voltage motor general electric power supply voltage is 6KV, low voltage motor is commonly 220V / 380V. The structure comes in, the high voltage motor is synchronous and asynchronous machine, low voltage motor is asynchronous motor.
Q:How is the servo motor parameter chosen
Call the servo factory, find a sample data, you can choose the requirements of your equipment
Q:How is the rated current of the three-phase machine calculated?
In general applications, you can estimate for each kw = 2A current, which is one kilowatt and two streams. Three-phase 5KW motor, normal operating current is around 10A The rated current is the current of the wire The rating is 4.8 KW = 4,800 watts, divided by 3 over the voltage, 380 volts divided by the power factor divided by the efficiency over the square root of 3, to see if this is equal to the rated current 11.5 A. If you tell me the power factor and the efficiency, you can calculate it. The small power efficiency and power factor of three-phase asynchronous motor is generally at about 0.8, the grid voltage (380 v line voltage), according to the efficiency of calculation is 4800 watts divided by 380 divided by 1.732 divided by 0.8 0.8 divided by the power factor is equal to about 11.5 amps. In the wrong place, please correct me.
Q:There is a difference between the electric motor and the other motors
So the torque output of the motor is going to get a good linear output, and the dynamic and the startup performance can be improved. This is only my opinion, for reference only
Q:Can variable frequency control motor be used as a general motor?
It should be possible because the converter also needs to be running at 50HZ The question becomes the answer The BM type is the rated frequency 50HZ frequency conversion asynchronous motor
Q:Is there any difference between motor and motor? A positive answer
Electric motors include motors and generators. The general term for generators and motors is that they are conceptually different. However, certain motors, such as synchronous motors, are generally more used as generators, but can also be used directly as motors. Asynchronous motors are more used for motors, but by adding simple peripheral components, they can also be used as generators.
Q:What is the solution to other circuit boards when the servo motor is turned on
On the servo drive power reactor with servo filter, and the circular filter, harmonic suppression measures, such as zero phase filter or is to add the device to the output of the servo driver try.
Q:My electric car rides on the motor and doesn't turn
Check for good or bad. When the hall element is damaged, the control function is lost. Check the brake switch. The action of the left and right brake switch is to disconnect the motor power when braking. So the switch is broken and the motor is not electrified. 3, check motor and electrical circuit leads. Due to the high current of electric current and vibration, the possibility of fracture and contact is present. In addition, motor damage is not excluded.
Q:What is the electric motor in the car seat?
The two lines are the wires of the motor rotor, and the three lines are the line of the motor controller (the seat control switch is connected to the controller of the seat motor to be controlled before and after the motor is controlled).
Q:What is the difference between the decelerating step motor and the normal step motor?
The decelerating step motor is the step motor of the decelerating mechanism. Adjust the torque. Some situations don't need fast speed but require great torque. There is also a large jump in the step motor at low speeds, which can be improved by adding a reducer.
