微型电动机是四驱车的心脏。电池为电动机提供转动的能源。经过减速齿轮变速,驱动四个轮子而使车辆跑动。用于四驱车的电动机(俗称马达)属130型,工业标准已经给它的外形,尺寸和主要结构都已作了严格规定,不能随便改动。但是它的转子绕组,换向器和电刷可适当改变。因而出现高、中、低转速和大、中、小转矩性能不同的电动机。 Micro motor is the heart of four-wheel drive. The battery provides the motor with rotational energy. After the reduction gear shift, driving the four wheels to run the vehicle. For four-wheel drive motor (commonly known as motor) is 130, the industry standard has given its shape, size and main structure have been strictly regulated, can not be arbitrarily changed. However, its rotor winding, commutator and brush can be changed appropriately. Thus there are high, medium and low speed and large, medium and small torque performance of the motor.
