We know that the single-phase motor can turn positive and negative, but under normal circumstances the spindle steering is positive, can be divided into running capacitance, starting capacitance, and no capacitance of the shield motor; So today, Senli Motor Xiaobian will take you to a simple understanding of the positive and negative conversion mode of single-phase asynchronous motors.

Motor positive and negative control, the phase sequence of the power supply can be any two relative adjustment, called commutation, usually V phase unchanged, through U and W switching, in order to ensure that the two contactors can reliably exchange the phase sequence of the three-phase asynchronous motor, wiring should make the contactor's upper connection consistent, in the contactor's lower port phase adjustment.

Torque, refers to the force of the transmission; A motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Torque motor torque in the circuit with the letter M (the old standard with D), its main role is to produce driving torque, as a power source for electrical appliances or various machinery.

The vertical motor and the horizontal motor have obvious differences in appearance, the vertical is fixed with the shaft end flange, and the horizontal organic seat is fixed. The same type of product, in the difference between the two installation methods, you can see whether the appearance of the torque motor is connected by flange or fixed by the frame.

Three-phase asynchronous motor We can invert the phase difference of 120° by commutation, then what is the requirement of single-phase asynchronous motor inversion? The following Senli motor Xiaobian will explain briefly for you.

The motors used by winding equipment manufacturers are generally torque motors that can be controlled by constant tension, so you know how to wire, and what problems should we pay attention to when wiring? Then Senli Motor Xiaobian will take you to a simple understanding of the details.

Three-phase asynchronous AC motor by simultaneously accessing 380V three-phase AC power supply, belongs to a kind of induction motor, because the rotor and stator rotating magnetic field in the same direction, different speed rotation, so there is a slip rate, so the name asynchronous. Here is a simple understanding of the requirements of Senli Motor.

Squirrel-cage three-phase asynchronous motor refers to a three-phase distributed winding on the stator of the motor and a cage guide bar on the rotor. Because the shape of the guide bar is similar to the squirrel cage, it is called the squirrel cage asynchronous motor. Here is a simple understanding with Senli Motor Xiaobian!

The general three-phase asynchronous motor will rely on inertial rotation for a period of time to stop after cutting the power supply, and in some cases need to use precise positioning, which requires braking of the motor. Braking is to give the motor a torque in the opposite direction of rotation to stop it quickly (or limit its speed).

The torque motor is mostly used in the case of constant torque, and the structure is simpler than that of the servo motor. The main feature of the torque motor is that it has soft mechanical characteristics. When the load torque increases, the speed can be automatically reduced and the torque output can be increased. Here is a simple understanding of the motor with Senli Small Editor.
