減速電機　Gear motor

減速電機是指減速機和電機(馬達)的集成體。這種集成體通常也可稱為齒輪馬達或齒輪電機。

通常由專業(yè)的減速機生產(chǎn)廠進行集成組裝好后成套供貨。減速電機廣泛應(yīng)用于鋼鐵行業(yè)、機械行業(yè)等。使用減速電機的優(yōu)點是簡化設(shè)計、節(jié)省空間。

 Gear motor means the integration of gear reducer and motor.This integration can normally be refered to as geared motor.
Supply after integrating,assembling by professional manufacturers of gear motor.Geared motor are widely used in steel industy,machinery industry and so on.The advantage of gear motor is to simplify design and save space.

直流無刷電機　Brushless dc motor

無刷直流電機由電動機主體和驅(qū)動器組成，是一種典型的機電一體化產(chǎn)品。由于無刷直流電動機是以自控式運行的，所以不會象變頻調(diào)速下重載啟動的同步電機那樣在轉(zhuǎn)子上另加啟動繞組，也不會在負載突變時產(chǎn)生振蕩和失步。中小容量的無刷直流電動機的永磁體，現(xiàn)在多采用高磁能積的稀土釹鐵硼（Nd-Fe-B）材料。因此，稀土永磁無刷電動機的體積比同容量三相異步電動機縮小了一個機座號。

Brushless dc motor is composed of motor main part and drive,which is a typical mechatronic products.Since the brushless dc motor operate based on self-control operation,it will not start additional winding like overloaded and started synchronous motor under frequency control,also it will not produce oscillations and step out when the load mutates.Small-capacity permanent magnet of brushless dc motor,now more used by high magnetic rare earth neodymium iron boron(Nd-FeB)material.Thus,the volume of rare earth permanent magnet brushless dc motor is reduced by more than a frame size compared with the same capacity of a three-phase asynchronous motors.

微型直流電機　Micro motor

1.微型直流電機的效率一般都要高于其他類型的電機，所以達到相同的輸出功率，直流電機的體積一般都比較小。對于安裝位置有限的情況下，微型直流電機相對比較合適。

2.微型直流電機有個特點是電機可以根據(jù)負載大小，自動降速，來達到極大的啟動扭矩。這一點交流電機就比較困難。另外直流電機比較容易吸收負載大小的突變，電機轉(zhuǎn)速可以自動適應(yīng)負載大小。

1,micro dc motor efficiency in general are higher than other types of motors,so achieving the same output power,the volume of dc motors are generally small.In the cased of limited installation position,micro motor is relatively appropriate.

2,The micro motor has a characteristic that motor can automatically speed down according to load size to achieve maximum starting torque,The ac motor is difficult regarding this point.Also dc motor is easier to absorb sudden changes of the size of load,and the motor can automatically adapt to the load size
