The difference between DC motor and AC motor
DC motor is a motor that can realize the mutual conversion of DC motor and mechanical energy, when mechanical energy is converted into electrical energy. The working principle of the DC generator is the principle that the alternating electromotive force induced in the armature coil is changed into a DC electromotive force when the commutator cooperates with the commutation effect of the brush.

Motor Efficiency in Ground Source Heat Pump System
All kinds of motors used in the ground source heat pump system can be divided into two categories according to the working efficiency of the motor: standard efficiency motor and high efficiency motor. Compared with the standard efficiency motor, the high efficiency motor can be 2 to 10 percentage points higher according to the power. The high efficiency motor is realized through better design and the use of special materials that can reduce the loss, but the price is about 10% to 30% of the standard efficiency motor. Therefore, only 1/5 of the motors sold in the world are high efficiency motors. Motor efficiency is the ratio of mechanical power output to power input, usually expressed as a percentage, and Figure 1 shows the difference between a standard motor and a high-efficiency motor, which is produced by improved design materials and technology to produce more work per unit of power consumption.

What is the cause of the abnormal sound of the motor and its treatment method?
The abnormal noise of the motor usually refers to the abnormal noise emitted by the motor during operation, which may be caused by the failure or damage of some parts of the motor.
