How To Repair Evaporative Cooler Motors

Evaporative coolers use 115/120 volt motors that operate on a comparatively low level of electricity compared to 240 volt central air conditioning systems. Unlike central air conditioners, however, evaporative coolers do not gradually degrade as a result of a breakdown. This means that you can often... read more

What are the types and compositions of commutators commonly used in single-phase series motors?

The commutator is a key component of the air conditioner motors, and its technical performance indicators and product quality directly affect the overall performance of the motor. When the motor rotates, the brushes commutate on the surface of the commutator, and frequent friction generates heat. Th... read more

Why are the mechanical properties of single-phase series motors soft?

Since the cooler motors is running, when the load torque increases, the electromagnetic torque increases, and the input current also increases. At the same time, because the excitation current of the series motor is equal to the total current of the armature, it is equal to the input current. Theref... read more
