微型减速电机的励磁方式可以使用哪些?

励磁就是向发电机或者同步电动机定子提供定子电源的安装。依据直流电机励磁方式的不同,可分为它励磁,并励磁,串励磁,复励磁等方式,直流电机的转动过程中,励磁就是控制定子的电压使其产生的磁场变化,改动直流电机的转速,改动励磁同样起到改动转速的作用。
Excitation is the installation of stator power supply for generator or synchronous motor stator. According to the different excitation modes of DC motor, it can be divided into its excitation, parallel excitation, series excitation and compound excitation. In the process of DC motor's rotation, excitation is to control the voltage of stator to change the magnetic field, to change the speed of DC motor, to change the excitation also plays a role in changing the speed.
微型减速电机的4种励磁方式:
Four excitation modes of miniature reducer motor:
1、它励磁
1. Its excitation
励磁绕组与电枢绕组无联接关系,而由其它直流电源对励磁绕组供电的电机称为它励电机,永磁电机也可看作他励或自激电机,普通直接称作励磁方式为永磁。
There is no connection between the excitation winding and armature winding. The motor supplied by other DC power supply to the excitation winding is called the other excitation motor. Permanent magnet motor can also be regarded as the other excitation or self-excitation motor, which is directly called the permanent magnet excitation mode.
2、并励磁
2. Parallel excitation
并励电机的励磁绕组与电枢绕组相并联,作为并励发电机来说,是电机自身发出来的端电压为励磁绕组供电;作为并励电动机来说,励磁绕组与电枢共用同一电源,从性能上讲与他励直流电动机相同。
The excitation winding and armature winding of shunt excitation motor are connected in parallel. As a shunt excitation generator, the terminal voltage from the motor itself supplies power for the excitation winding. As a shunt excitation motor, the excitation winding and armature share the same power supply, and the performance is the same as that of the other excitation DC motor.

3、串励磁
3. Series Excitation
串励电机的励磁绕组与电枢绕组串联后,再接于直流电源。这种电机的励磁电流就是电枢电流。
The excitation winding of the series excitation motor is connected in series with the armature winding, and then connected to the DC power supply. The excitation current of this kind of motor is armature current.
4、复励磁
4. Compound excitation
复励电机有并励和串励两个励磁绕组。若串励绕组产生的磁通势与并励绕组产生的磁通势方向相同称为积复励。若两个磁通势方向相反,则称为差复励。
The compound excitation motor has two excitation windings: parallel excitation and series excitation. If the flux potential produced by series winding is the same as that produced by shunt winding, it is called cumulative compound excitation. If the direction of two flux potentials is opposite, it is called differential compound excitation.
为发电机等(应用电磁感应原理工作的电气设备)提供工作磁场叫励磁。有时向发电机转子提供转子电源的安装也叫励磁。
To provide the working magnetic field for generators (electrical equipment working with electromagnetic induction principle) is called excitation. Sometimes the installation of the rotor power supply to the generator rotor is also called excitation.
