Shaded pole motor specification

1) Voltage (V) means the motor in normal operation, the stator windings to be connected to the supply voltage. different countries and regions use a lot of different voltage, so the motor voltage specifications are also many, such as: 120V, 230V, 220V, 240V, 100V, etc., is also useful in industrial applications, 12V, 24V, 36V, 45V and so on. Supply voltage tolerance of not more than ± 5%.

2) Frequency (Hz) is the frequency of the AC power, China's power grid frequency is defined as 50 Hz, some country use 60 Hz. Frequency allows the deviation does not exceed ± 1%.

3) Power (W) means the motor is running at rated mechanical shaft output power.

Our company's (Ningbo Jant Electrical Appliance c Ltd.,)motor nameplate rated power generally refers to the maximum input power.

4) Speed ​​(RPM) indicates the motor at the rated voltage, frequency and output power to run the rotation speed. Typically, the motor speed is the speed of the motor shaft(no load), for some specialty products is often expressed through the output gear of the actual rotational speed of the shaft(on load), shaded pole motor speed is lower than the power supply frequency and Electric poles synchronous speed determined.

5) Current (A) refers to the motor is running at rated conditions stator windings of the input current can be used to check whether the motor is overloaded or defective.

6) Efficiency (η) means the motor is running at rated output power and input power ratio. Generally in the motor to reach thermal steady state, with a dynamometer directly measured the output torque and rated speed records to calculate the output power, while the motor power input is read directly from the test instrument.

7) Insulation class indicates the motor winding insulation level for determining the allowable temperature rise of the motor, commonly used insulation levels are A, E, B, F, and H five, corresponding to the maximum operating temperature of 105 ℃, 120 ℃, 130 ℃, 155 ℃ and 180 ℃.

8) Some other indicators have been specially designed or special use of the motor, but also marked on the nameplate on the technical indicators, such as work methods (continuous, short-term, intermittent cycle operation), the thermal protection in the form (impedance protection, disposable thermal Insurance protection, etc.), power factor, starting current and torque overload factor and so on
