Q:What is the difference between a single phase motor and a two-phase machine?
Single-phase motor is to use the 220 power supply, three-phase motor is to use the three phase line of power supply, no dual phase motor, only electric welding machine is to use two phase 380 v electricity
Q:Which is good for the washing machine series motor and general motors?
Principle of general motors: the direction of force of conductor is determined by the left hand. This pair of electromagnetic force formed on the armature a torque, the torque in rotary motor is called electromagnetic torque, torque direction is counterclockwise, trying to make the armature counterclockwise rotation. If the electromagnetic torque can overcome the armature resistance torque (for example, caused by friction resistance torque and other load torque) and the armature can spin counterclockwise direction.
Q:What is the difference between a speed reducer and a regular motor?
If you're talking about a speed reducer, you can compare it to a regular motor Deceleration motor called gear motor, gear motor, reducer and motor assembly, are modular combination, common ordinary motor is 4 (output synchronous speed 1500 RPM), 6 (output synchronous speed 1000 RPM), 8 (output synchronous speed 750 RPM), motor, including the most commonly used the 4 pole motor, the higher the number, the more expensive, due to the speed of the equipment is used generally smaller, and the output of the motor speed cannot meet the requirements of actual or torque, so through the gears or other institutions such as cycloid motor droop down, at the same time the output torque, in order to satisfy the needs of speed and torque
Q:What is the structural difference between a two-speed motor and a regular motor
There are two sets of coils in the two-speed motor slot, and the ordinary motor has a set of coils through the special switch control speed. This is the main difference.
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 difference between a step motor and an ordinary motor
The step motor is in the position control general motors are usually the speed control and the control of the two is different. Position control means that you can set the number of times you want your motor to rotate (a circle of 360 degrees), and speed control means how much your motor is going to turn/minute. This can be seen in the low speed of the step motor, which is the high speed of the motor.
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: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:What is the difference between a carbon brush motor and a regular motor. Which machine is better
Have carbon brush motor is generally dc motor, compared with the ordinary ac motor, the working principle, scope of application is different, have different application scope, there is no who good who bad, ac asynchronous motor has simple structure, the manufacturing cost and use cost are bottom
Q:What is a permanent magnet motor? Is there a difference between a regular motor
The difference between a permanent magnet and a conventional motor is: Magnetic field properties. Permanent magnet motors are made without the external energy to maintain their magnetic field; Ordinary motors require electricity to flow in to have a magnetic field. Rotor structure. The permanent magnet motor rotor is fitted with a permanent magnet. Excitation coil is installed on ordinary motor rotor. Applicable occasions. Permanent magnet motors are used for small power occasions; General motors, especially exciter motors, are often used in high-power situations. Electric machinery, electric machinery, is an electromagnetic device that realizes electrical energy conversion or transmission according to electromagnetic induction law. In the circuit, the letter M indicates that its main function is to generate drive torque as the power source of electrical or mechanical power.
