The main difference between brushless DC motor and DC servo motor

Different definitions: (1) Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as commutator less motor. As early as the 19th century, when the motor was born, the practical motor was the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. The transistor was born in the middle of last century, so the brushless DC motor using transistor commutation circuit instead of brush and commutator came into being. This new type of brushless motor is called electronic commutation DC motor, which overcomes the defects of the first generation of brushless motor.

Common practice of oil return design in refrigeration system

When the condenser is installed higher than the compressor, a U-shaped bend is required at the intake pipe of the condenser to prevent oil from returning to the exhaust side of the compressor during shutdown and also help prevent liquid refrigerant from the condenser

Heat Pump vs Central Air: Which One is Right for You?

When it comes to cooling your home, you have two main options: a heat pump or a central air conditioner. Both systems work to remove heat from your home and circulate cool air throughout, but they operate in different ways.

What if the compressor burns out

What if the compressor burns out Why does the compressor burn the motor? What caused the burn-in phenomenon? The summary of the reasons for motor burning can be divided into: load, power supply, motor insulation, and lack of equality.
