Permanent magnet DC motor in the usual use of the process should pay attention to these issues (1) If the product is not specified, under normal circumstances (such as aluminum-nickel-cobalt permanent magnet DC motor or ferrite permanent magnet DC motor) permanent magnet DC motor are not allowed
The DC motors with different excitation have different characteristics. In general, the main excitation mode of the DC motor is the seperately excitation, the series excitationand the compound excitation . The main excitation of the DC generator is the seperately excitation. DC motor features: (A
Failure mode operation of high - voltage AC Motor with fan Symptoms: The AC Motor can not start, even if no load can start, the speed slowly rise, there is buzz; motor smoke fever, and accompanied by burning smell. Test result ： Remove the AC Motor cover, you can see the end of the win
High-voltage AC Motor start ways:1, autotransformer decompression start and reactor buck start compared to get the same starting torque in the case of autotransformer-type step-down start of the start-up current is small, suitable for large resistance torque situation.2, the motor full pressure star
1. High-voltage Induction AC Motor bearing heat generation phenomenon High-voltage motor by coupling parts of the phenomenon of heat, stop check and found that each time the coupling should be removed, need more than 8 hours, the maximum bearing temperature of 118 ℃, circulating fan bearing heat
