Q:How do you think a motor is an ordinary motor or a servo
Different methods: Common motor is a radiator in the rear, general motors are cast iron case The servo motor is a coder with no cooling fan, usually aluminum Servo motor Open classification: machine, motor Noil definition: the engine that controls the operation of the mechanical component in the servo system. Noil effect: servo motor, can make control speed, position precision is very accurate. The voltage signal is converted into torque and rotational speed to drive the control object Noil classification: dc servo motor and ac servo motor.
Q:Direct drive motor control mode
So there is no such thing as "the frame type is the control mode of the permanent magnet synchronous motor, the no-frame type is the control mode of dc brushless motor". Perhaps your motor coincided with a particular type of "frame with permanent magnet synchronous motor control mode" or the different type of brushless dc motor control way ". In fact, permanent magnet synchronous motor control method and two kinds of brushless dc motor control method in most cases is one thing, there is not much difference.
Q:Which is good for common motor and induction motor?
Induction motor, also called "asynchronous motor, the rotor put in a rotating magnetic field, under the effect of rotating magnetic field, to obtain a rotational torque, thus the rotor rotation. The rotor is a rotating conductor, usually in a squirrel-cage. It was invented by electrical engineer nikola tesla in 1887.
Q:What is the difference between an energy-saving motor and a general motor
Features of high efficiency energy-saving motor: 1, save energy and reduce long-term operation cost, very suitable for textile, fan, water pump, compressor, power saving a year recoverable motor acquisition cost. The machine can be switched on and off, and the asynchronous machine can be replaced completely. 3, rare earth permanent magnet high efficiency and energy saving motor itself than ordinary more than 15 ℅ save power. The power factor of the motor is close to 1, improving the quality factor of the power grid without the power factor compensator. Small electric current, saving power distribution capacity and extending the overall operating life of the system.
Q:The difference between ordinary motor and permanent magnet motor
There are two different kinds of classifications that you can't compare. Permanent magnet motor is called permanent magnet motor, not permanent magnet (electromagnet) for permanent magnet. Dc motors with direct current, no direct current (alternating current) is ac motor. A permanent magnet can be a dc motor or ac motor (for example, a home breeze fan). In the same way, no permanent magnet can be either a dc motor or ac motor, or even an alternating current.
Q:What's wrong with the rotary roller
The machine burns a set of lines, which may be the starting line. 2, the motor card is dead, try to turn by hand. Check the capacitance or change it. The main board is broken, and it cannot detect the starting signal.
Q:What is the difference between servo motor and general motors?
Servo motors belong to precision motors, and the smaller power, have their own Angle feedback signal, each round will produce more than 10000 Angle signal, extremely accurate, generally used in precision machining, special equipment, use to have a high precision requirement, general motors just a equipment of electrical energy into kinetic energy, there is no other auxiliary functions
Q:How is the rated current of the three-phase machine calculated?
Three-phase motor power P = 1.732 UIcos phi, cos phi (power factor) between 0.7 and 0.95, the greater the power of the motor, the greater the power factor, which can be evaluated at 0.85. So I = P/(1.732 * U * cos phi) = 4800 / (1.732 * 440 * 0.8) = 1.732 A, 11.5 A you say may be the whole compressor power or are you using current meter measuring current, if the current meter measurement, so the motor is overload. Voltage is 440 v, can know you this motor is not domestic, domestic general is 380 (400 v), rated 400 v voltage can be used in our country, of course, because the motor is a range of voltage, rated voltage 400 v motor between 360-440 - v can be used. In China there is 440 v, you said general voltage is 380 v, 440 v rated voltage, so when calculating the electric current cannot use the above data, and should change the 440 to 440, the calculated current is 9.1 A. Here's a rough calculation, because 1.732 * 380 * 0.8 = 520, close to 500, so under the three-phase 380V voltage, Current I = P (kilowatt) / 2.
Q:How does servo motor understand? What is a servo motor?
Servo motor (servo motor) is the engine that controls the operation of mechanical components in servo systems. The servo motor can control the speed, the position precision is very accurate, can convert voltage signal to torque and speed to drive the control object. Servo motor rotor speed controlled by the input signal, and can be rapid response, in the automatic control system, is used as actuators, and has a small electromechanical time constant, high linearity, initiating character such as voltage, can convert the received electrical signal to the motor shaft angular displacement or angular velocity on output. Divided into two major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform.
Q:Why is electric motors not rotating? Everything else is good.
The voltage should be greater than 36V (the battery is sufficient), and the input line should be checked if there is no voltage. Check the controller to turn the power supply voltage (switching of the red, black), normal voltage in 5 ~ 6 v, if there is no 5 v voltage, unplug the socket, restore 5 v voltage, hall element may be for motor short circuit, if still no 5 v voltage, is used as the controller, the controller should be replaced. First of all, check the speed of adjustment and the opening of the motor hall to have a short circuit.
