6 FAQs about [Normal voltage of energy storage motor]
What is the maximum voltage a motor can tolerate?
Thus, the actual voltage range that they can tolerate on the high voltage connections would be at least 207 volts to 253 volts. Even though this is the so-called tolerance band, the best performance of larger motors would occur at or near the rated voltage. The extreme ends, either high or low, would be putting unnecessary stress on the motor.
How many volts can a motor handle?
For example, many motors are rated at 220/230 volts and had a tolerance band of plus/minus 10%. Thus, the actual voltage range that they can tolerate on the high voltage connections would be at least 207 volts to 253 volts.
How much power should a motor have?
Considering the motor types for a representative manufacturer (1.5 kW, 2.2 kW and 3.0 kW), the best choice is a machine of the rated power of 3 kW. However, the machine will work with a load of approximately 50% of its full power, if the required mechanical power is correctly assessed.
What if a motor is over 230 volts?
This generally means that the motors will tolerate a certain change in voltage above the design voltage, but extremes above the designed voltage will cause the amperage to go up with a corresponding increase in heating and a shortening of motor life. For example, many motors are rated at 220/230 volts and had a tolerance band of plus/minus 10%.
What is the maximum voltage deviation for a low-voltage system?
For various low-voltage systems, the maximal permitted deviation of the utilization voltage is usually approximately −6%, +9.6% for Range A, and −9.6%, +10.4% for Range B. Voltage unbalance is recommended to be restricted to 3% and partly connected with voltage deviation (each phase voltage should be within the limits for Range A or Range B).
What if a motor voltage is below a rated voltage?
On many motors it might occur at a point 2% to 3% below the rated voltage. Also the rise in full load amps at voltages above the rated, tends to be much steeper for some motor winding designs than others.
