山东无刷电机的特性是什么?

来源:http://www.jnmcd.com 发布时间:2020-07-16 浏览:
1、电机体积小,重量更轻,对于异步电机,由于其转子是由带齿,槽的铁心构成,槽中用来安放感应绕组感应生成电流,产生转矩,所有转子的外径不能太小,有了有刷直流电机,电枢绕组放在转子上也无法将外径减小。同时机械换向器的存在也限制了外径的减小,而无刷电机的电枢绕组在定子上,因而转子的外径可以相对减小。
1. The motor is small in size and lighter in weight. For asynchronous motor, because its rotor is composed of iron core with teeth and slots, the slot is used to place induction winding to generate current and generate torque. The outer diameter of all rotors cannot be too small. With a brush DC motor, the armature winding on the rotor can not reduce the outer diameter. At the same time, the existence of mechanical commutator also limits the reduction of the outer diameter, and the armature winding of the brushless motor is on the stator, so the outer diameter of the rotor can be relatively reduced.
2、电机损耗小,这是由于取消了电刷,并采用电子换向取代机械换向,因此消除了电机的摩擦损耗和电损耗,同时转子上没有历磁绕组,因此消除了电损耗,历磁磁场不会在转子上产生铁耗。
2. The small loss of the motor is due to the elimination of the brush and the use of electronic commutation instead of mechanical commutation, so the friction loss and electrical loss of the motor are eliminated. At the same time, there is no calendar winding on the rotor, so the electric loss is eliminated, and the permanent magnetic field will not produce iron loss on the rotor.
3、电机发热小,这是由于电机损耗小,同时电机的电枢绕组在定子上,直接和机壳连,因此散热条件好,热传导系数大。
3. The low heating of the motor is due to the small loss of the motor, and the armature winding of the motor is directly connected with the casing on the stator, so the heat dissipation condition is good and the heat conduction coefficient is large.
4、效率高,虽然无刷电机应用很广,功率范围很大替代的电机种类不同,不一样的产品应用效率的提高也不同,在风机产品中可以实现效率的提高20-30%。
4. High efficiency, although the application of brushless motor is very wide, the power range is very large, the types of motor replaced are different, and the application efficiency of different products is also different. In fan products, the efficiency can be increased by 20-30%.
5、调速性能好,对于无刷电机通过电位器调节电压实现无级或者档位调速,还有PWM占空比调速以及脉冲频率调速。
5. For brushless motor, the voltage is adjusted by potentiometer to realize stepless or gear speed regulation, and PWM duty cycle speed regulation and pulse frequency speed regulation are also available.
6、噪音低,干扰小,能耗低,启动转矩大,没有换向带来的机械摩擦。
6. Low noise, small interference, low energy consumption, large starting torque, no mechanical friction caused by commutation.
7、可靠性高,寿命长,省去了电刷消除了电机主要故障的来源,电子换向电机发热降低,电机的寿命延长。
7. High reliability, long service life, no brush, eliminate the main source of motor failure, electronic reversing motor heat reduction, motor life extension.
8、地域优势:我国是稀土国,无刷电机采用稀土材料的研究在我国达到水平,因此无刷电机成本比国外的优势则更加突出,在我国带动无刷电机应用的发展具有先天条件。
8. Regional advantages: China is the kingdom of rare earth. The research on the application of rare earth materials in brushless motor has reached the international leading level in China. Therefore, the cost of brushless motor is more prominent than that of foreign countries. There are inherent conditions for driving the development of application of brushless motor in China.
