直流减速电机发热振动现象是什么原因引起的?

来源:http://www.jnmcd.com 发布时间:2019-01-07 浏览:
有些用户在使用直流减速电机的过程中会忽略直流减速电机的发热振动现象,但我不知道这是否是直流减速电机的故障。
Some users will neglect the vibration phenomenon of DC deceleration motor in the process of using DC deceleration motor, but I don't know if it is the fault of DC deceleration motor.
这也是识别直流减速电机质量的标准。那么,如何解决直流减速电机的振动和发热问题呢?以下小编将与您分享一些对策:
This is also the standard to identify the quality of DC deceleration motor. So, how to solve the problem of vibration and heat of DC deceleration motor? The following edition will share with you some countermeasures:
首先,微型齿轮电动机必须在定子绕组之间或相之间短路或接地,以便电流增加,损耗增加并且热量过热。如果故障不严重,只需重新安装绝缘层并严重更换绕组。
First, the micro gear motor must be short-circuited or grounded between stator windings or phases in order to increase current, loss and heat overheating. If the fault is not serious, just reinstall the insulation layer and replace the winding seriously.
二,轴承损坏或过度磨损,使定子与转子相摩擦,可检查轴承是否松动,定子和转子是否组装不当。
Second, bearing damage or excessive wear, so that the stator and rotor phase friction, can check whether the bearing is loose, whether the stator and rotor assembly is inappropriate.
3.如果电压超过直流电机额定电压的10%或低于直流电机额定电压的5%,则直流电机在额定负载下容易发热,温升会增加。应检查并调整电压。
3. If the voltage exceeds 10% of the rated voltage of the DC motor or is lower than 5% of the rated voltage of the DC motor, the DC motor will easily heat up under the rated load and the temperature rise will increase. The voltage should be checked and adjusted.
4.笼式转子断条或绕线转子线圈接头松动,导致维护网络电流过大而发热。铜带转子可以修理或更换,转子应更换为铸铝转子。
4. Cage rotor broken bar or winding rotor coil joint loosened, resulting in excessive maintenance network current and heat. Copper belt rotors can be repaired or replaced. The rotors should be replaced by cast aluminium rotors.
发热
fever
1.抑制转子不平衡。
1. Suppression of rotor unbalance.
2.维持在允许的不平衡范围内。
2. Maintain the allowable imbalance.
3.改善轴和铁芯的过度对齐。
3. Improve the over-alignment of shaft and core.
4.改善了热膨胀各向异性的设计。
4. The design of thermal expansion anisotropy is improved.
5.强度设计或装配的改进。
5. Improvement of strength design or assembly.
6.轴强度设计的校正,联轴器的类型变化和直线到中心的校正。
6. Correction of shaft strength design, type change of coupling and rectification from straight line to center.
7.防止轴承端面和轴附接部分或锁紧螺母偏置。
7. Prevent bearing end face and shaft attachment or lock nut offset.
