交流微型电机的类型包括:
The types of AC micro motors include:
同步:
Synchronization:
在这品种型的微型电动机中,转子的旋转与供电电流的频率同步,并且在变化的负载下速度坚持恒定,因而十分适用于以恒定速度驱动设备并且用于机器人等高精度的定位设备,仪表,机器和过程控制等。
In this type of micro-motor, the rotation of the rotor is synchronized with the frequency of the supply current, and the speed is constant under changing loads. Therefore, it is very suitable for driving equipment with constant speed and for high precision positioning equipment, instruments, machines and process control such as robots.
感应(异步):
Induction (Asynchronism):
这品种型的电动机运用来自定子绕组的磁场的电磁感应,以在转子中产生电流并因而产生扭矩。这些是最常见的交流微型电机类型,并且由于它们的负载才能而在工业中很重要,单相感应微型电机主要用于较小的负载,如用于家用电器,而三相感应微型电机更多地用于工业应用,包括像紧缩机,泵,保送系统和起重设备等。
This type of motor uses electromagnetic induction from the magnetic field of the stator winding to generate current and thus torque in the rotor. These are the most common types of AC micro-motors and are important in industry because of their load capacity. Single-phase induction micro-motors are mainly used for smaller loads, such as household appliances, while three-phase induction micro-motors are more used for industrial applications, including compressors, pumps, delivery systems and lifting equipment.

山东微型电机
直流微型电动机是一种普遍运用的微型电动机,系统(电动机和驱动器)的初始本钱通常低于低功率单元的交流系统,但是功率越高,总体维护本钱就越高,需求加以思索。直流微型电机的速度能够经过改动电源电压来控制,并且能够在很宽的电压范围内运用,但最盛行的类型是12V和24V,其中一些优点是:
DC micro-motor is a kind of widely used micro-motor. The initial cost of the system (motor and driver) is usually lower than that of the AC system with low power unit. However, the higher the power, the higher the overall maintenance cost and the need to think about it. The speed of DC micro motor can be controlled by changing the supply voltage and can be used in a wide range of voltage. But the most popular types are 12V and 24V. Some of the advantages are:

Two common types are:
有刷
Brush
这些是更传统的微型电机类型,通常用于本钱敏感的应用,其中控制系统相对简单,例如在消费者应用和更根本的工业设备中,这些类型的微型电机能够合成为:
These are more traditional types of micro-motors, usually used in cost-sensitive applications, where control systems are relatively simple, such as in consumer applications and more fundamental industrial equipment, these types of micro-motors can be synthesized into:
系列绕组 - 这是励磁绕组与转子绕组串联衔接的中央,速度控制是经过改动电源电压,但是这品种型提供了较差的速度控制,并且当微型电机的转矩增加时,速度降落。应用包括汽车,起重机,升降机和起重机,由于它具有高启动扭矩。
Series windings - This is the center of the series connection between the excitation winding and the rotor winding. The speed control is by changing the power supply voltage, but this type provides poor speed control, and when the torque of the micro motor increases, the speed falls. Applications include automobiles, cranes, lifts and cranes because of their high starting torque.
分流绕线 - 这品种型有一个电源,励磁绕组与转子绕组并联衔接,能够进步转矩,而不会经过增加微型电机电流来降低速度。它具有中等程度的启动扭矩和恒定速度,因而适用于车床,真空吸尘器,保送机和研磨机等应用。
Shunt winding-this type has a power supply, and the excitation winding is connected in parallel with the rotor winding to improve the torque without increasing the current of the micro motor to reduce the speed. It has moderate starting torque and constant speed, so it is suitable for lathe, vacuum cleaner, delivery machine and grinder applications.
复合伤口 - 这是串联和分流的累积,其中分流绕组的极性使其增加到串联场。假如负载略有变化,这品种型具有较高的启动转矩并可平稳运转,用于驱动紧缩机,可变头离心泵,旋转压力机,圆锯,剪切机,电梯和连续保送机
Composite wound - This is the accumulation of series and shunt, where the polarity of shunt windings increases to the series field. If the load changes slightly, this type has high starting torque and can run smoothly. It is used to drive compactors, variable head centrifugal pumps, rotary presses, circular saws, shears, elevators and continuous conveyors.
永磁体 - 它不是电磁体,运用永磁体,用于准确控制和低扭矩的应用,例如机器人系统。
Permanent magnet - It is not an electromagnet, using permanent magnets for accurate control and low torque applications, such as robotic systems.
无刷
Brushless
无刷微型电机减轻了与更常见的有刷微型电机相关的一些问题(高运用率应用的短寿命)并且在设计上机械上更简单(没有电刷)。微型电机控制器运用传感器检测转子位置,运用此控制器能够经过转子线圈中的电流准确控制微型电机,以调理速度。该技术的优点是寿命长,维护少,效率高(85-90%),但缺陷是初始本钱较高,控制器更复杂。这些类型的电动机通常用于速度和位置控制,适用于需求牢靠性和巩固性的风扇,泵和紧缩机等应用
Brushless micro motors alleviate some of the problems associated with more common brushless micro motors (short life in high utilization applications) and are mechanically simpler in design (no brushes). The micro motor controller uses sensors to detect the position of the rotor. The controller can accurately control the micro motor through the current in the rotor coil to adjust the speed. The advantages of this technology are long life, less maintenance and high efficiency (85-90%), but the disadvantages are higher initial cost and more complex controllers. These types of motors are commonly used for speed and position control and are suitable for applications such as fans, pumps and compressors that require strong reliability and consolidation.
