Q:The difference between pulse motor and servo motor
But if you ask the difference between the stepping motor and the ac servo or dc servo, I can tell you: Stepper motor start-up needs a slow speed, and can control through pulse, and is inversely proportional to the speed and torque of the motor, the higher the speed, torque is smaller, and the highest speed is not more than 1500 r and his itself has no feedback device, speed up the easy step, and the low speed easy to shake. And other kinds of motor position control (pulse) and speed (analog control) with a feedback device, constant torque under the rated speed, the speed of tens of thousands of turn, and because there are feedback device step will not be lost
Q:What is the difference between a three-phase asynchronous motor and a regular motor?
Torque motor: a special motor with soft mechanical properties and wide speed range. This motor is not powered by constant power output but by constant torque output. Torque motor includes: dc torque motor, ac torque motor, and brushless dc torque motor. Difference: torque motor is to in the case of lower speed without changing the output torque, motor speed when lowering power supply voltage drops, but the output torque constant, current is the same. Ordinary motors cannot be slowed down by reducing pressure, which will cause the output torque to decrease and the current increase, which will burn the motor. Change frequency converter control: to confirm the torque motor that is controlled is ac asynchronous motor or synchronous motor because the frequency converter is used on ac. It is also important to confirm that the maximum current of the frequency converter is greater than or equal to the current of the torque motor, since the torque motor is able to work in a blocked state.
Q:What is a hydraulic motor
No hydraulic motor of this statement, first of all, the mean power as the driving force of mechanical, electrical and hydraulic two different drive mode, only the hydraulic pump and hydraulic motor, hydraulic pump is driven by motor, have a plenty of driven by hydraulic motor,
Q:What is the solution to other circuit boards when the servo motor is turned on
First, the grounding of the servo drive. Second, if conditions permit, it is recommended to replace the power supply of the servo driver to a shield wire and provide a reliable grounding to the shield.
Q:How does the heat of dc motor control
70-90 ℃ belongs to the normal phenomenon, as long as less than 130 ℃, generally do not have what problem, if you really feel overheated, the drive current set the speed of the motor about 70% of the rated current or reduce one Some. When there is no failure, it is normally warm. Of course, the normal heat won't be too hot. Normal fever: One, the coil has the resistance, the current flows through the loss power; The magnetic field of the iron core has a "hysteresis loop". The iron core and the vortex, the magnetic energy that turns the electric energy into a part of the magnetic energy that becomes electric current and then becomes heat energy; There is friction between the mechanical rotating parts, and a part of the kinetic energy of the transition continues to change to heat energy.
Q:Can ac servo motor be used as ordinary motor?
Do you mean the common ac asynchronous motor should be the motor? Is not driving motor is usually three or single motor ac servo machine is two in terms of working principle Ac servo machine belongs to control the motor Smaller than the drive motor to drive the load
Q:What is the difference between special motors and ordinary motors?
Working principle: Electric motor: turn the electric flow into mechanical energy and turn the external object Generator: using electromagnetic induction to convert mechanical energy into electricity. It's not the equivalence between the motor and the generator! There is a reversibility between the motor and the generator! In the process of use, we combine them to not become a perpetual motion machine because of the conservation of energy.
Q:The ordinary motor is adjusted by the frequency converter
When the torque is greater than the load, the frequency can reach the limit, higher than the constant power characteristic, and the real-time current is not overrated. The change of motor is just a consideration of the torque
Q:The advantage of the pole motor relative to the ordinary motor
For users, the only benefit of a pole machine is the cheap. The pole type motor is the simplest form of a one-way ac motor. The advantage of a pole machine is that it is simple in structure, without the addition of a starting winding and starting capacitor. The drawback is that it's inefficient and it's bad. If the environment is harsh and closed, it should be considered that the electromagnetic load is low because it is difficult to heat the heat. Or, you could think of a slightly more powerful machine.
Q:How do ordinary motors achieve precise positioning
Ordinary motors can be accurately positioned through a series of circuits. Specific as follows: In action slider side low add a micro switch, micro switch control an intermediate relay, in the middle of the normally closed contact is broken the power of the motor, and at the same time delay relay through 3 s, the use of time relay normally open point back to the motor power supply. The highest point also can add a microdynamic switch the principle is the same! This completes the basic positioning control circuit and the lowest cost.
