What is Wind Turbine?

The structure of a small wind power generation system is generally composed of a wind turbine , a generator, a rudder and an electrical control part. Conventional small wind turbines are mostly composed of induction generators or permanent magnet synchronous generators and AC/DC converters, batteries and inverters. In the blowing wind, the wind wheel rotates, turning aerodynamic energy into mechanical energy. The hub of the wind wheel is fixed on the generator shaft and the rotation of the wind wheel drives the rotation of the generator shaft, driving the permanent magnet three-phase generator to generate three-phase alternating current (AC). The wind speed changes continuously and the current and voltage generated by the generator also change accordingly. The generated electricity is rectified by the controller, is changed from alternating current (AC) to direct current (DC) with a certain voltage, make the battery charged. The direct current output from the battery pack is transforme...

What Causes an Vibration Motor to Overheat?

Generally speaking, a vibration motor has a certain operating power, which is called the rated power, the unit is watts (W). If the actual motor power exceeds the rated power of the vibration motor in some cases, this phenomenon is called motor overload. The following is the reasons for the vibration motor overload. 1. Overload. 2. The voltage of the vibration motor is too high or too low. 3. The vibration motor is severely damp or corroded by corrosive gas for a long time, which reduces the insulation resistance. 4. The bearing of the vibration motor lacks of oil or is under dry grinding situation. Additionally, the rotor is mechanically misaligned, causing the motor current to exceed the rated value. 5. Failure of the mechanical transmission parts happens. 6. Analysis of other causes of vibration motor overload. The terminal voltage is too low. This voltage refers to the voltage measured at the lead end of the motor stator when the vibrating motor is starting or running at full load,...
