Concerns as well as answers about basic electric motor understanding
It is usually needed to dismantle the motor when servicing the motor. If it is poorly gotten rid of, it will damage the motor. As a result, motor maintenance employees have to understand the innovation to appropriately take apart and assemble the motor. The complying with steps need to be taken when taking apart the motor:
What is the absence of stage?
A: One stage of the three-phase circuit of the brushless motor or the brushless controller can not work. The absence of phase division primary phase phase loss as well as Hall phase loss. It appears that the motor shake can not function, or the rotation is weak and the noise is loud. The controller works quickly in the phase loss state and also is conveniently shed.
5 Before dismantling the side cover of the commutator, mark the joint between the end cover and also the base, after that pad the board, and also uniformly touch the edge of completion cap with a hammer to make the end cover slowly detach from the base as well as Bearing outer ring. Mark the brush holder setting as well as eliminate the brush holder.
02
Undervoltage protection
When the grid voltage decreases, the electric motor runs under undervoltage. Because the motor lots does not transform, the motor torque decreases under undervoltage, as well as the stator winding existing increases, which impacts the normal operation of the motor or even damages the electric motor. At this time, the power supply is removed by the defense device for undervoltage protection.
03
Loss of stress security
When the production machinery is working, the power grid all of a sudden sheds power for some reason. When the power supply is recovered, the defense electrical home appliance must ensure that the production machinery can be rebooted before it can run, and it will not cause individual and also tools mishaps. This protection is pressure loss (absolutely no stress). )security. Electric appliances that accomplish voltage loss (zero stress) protection have contactors as well as intermediate relays
The three-phase AC motor is mainly made up of a stator and also a rotor. When a three-phase alternating existing is applied to the stator, a rotating magnetic field is created. The magnetic field constantly has two poles (also probably in sets), specifically the N post (north post) and the S post (north pole), additionally known as a counter post. When the winding setting of the A/C electric motor stator winding is different, the number of magnetic poles of the created rotating magnetic field is different. The variety of posts directly influences the speed of the electric motor. Their connection is: synchronous rate = 60 × regularity/ degree logarithm. If the concurrent rate of the motor is 1500 rpm, the post pair number can be determined according to the above equation, which is a 4-pole electric motor. The simultaneous speed and also the variety of pole pairs are the standard parameters of the electric motor and also can be discovered on the nameplate of the electric motor. Since the post pair can influence the rate of the electric motor, you can transform the rate of the motor by transforming the pole set of the motor.
7 Eliminate completion cap screws on the expansion side of the shaft and also draw the armature together with completion cap from the stator core. Take care not to harm the armature winding during operation.
The safety electric device is utilized to make sure that the DC electric motor works under a magnetic field of a certain strength, so that the electromagnetic field is not damaged or vanished, as well as the motor speed is protected against from rising quickly, and also also a flying phenomenon takes place. This defense is weak magnetic security.
The provided regularity magnitude as well as the starting current dimension are not necessarily relevant. The magnitude of the starting current depends upon the setting of the starting V/F contour and also the length of the acceleration time. For fluid tons, the torque called for during operation is not consistent. Consequently, using multiple power curves can make the tools run even more energy-efficient and bring financial advantages to customers.
In the work, everyone should have come across a lot of electric motor burning, some because of mechanical problems, some because of the heat problem, and some because of the lack of phase and also burned.

Answer: When the electric motor is functioning, the coil and the commutator turn, the magnetic steel as well as the carbon brush do not revolve, as well as the alternating present instructions of the coil is completed by the commutator and also the brush that revolve with the electric motor. Brush motors in the electrical lorry sector are split into high speed brush electric motors as well as low speed brush electric motors. There are numerous differences in between brush motor and brushless electric motor. It can be seen from the word that the brush electric motor has a carbon brush, as well as the brushless electric motor has no carbon brush.
