a motor is determined by the power supply and the number of poles built into the structure of the winding. With a 60 cycle power supply the synchronous speeds available are 3600 RPM, 1800 RPM, 1200 RPM and 900 RPM. Induction motors develop their torque by operating at a speed which is slightly less than synchronous speed.

The speed a synchronous motor will run can be determined by the number of poles of the motor and the frequency of the electrical service using the formula: RPM = Hz* (2 / poles) * 60. where. RPM = shaft rotation speed or revolutions per minute. Hz = frequency or cycles/sec. Poles = number of poles of your motor.

It is an easy mistake to believe that a 400 hp 1200 rpm motor, which would ... for the motor vendor to design the motor appropriately. The following table details alternate starting methods, with resultant motor torque ...

An electric motor's nameplate or rated power is its output power, not its electric input power. Electric power consumption is rated power divided by motor efficiency. Rated power depends on class of motor (which considers intended duty). Industrial grade motors usually are rated for continuous duty.

hp to amperes (horsepower → amps), with this calculator you can easily convert, here you will find the main formula, how to perform the conversion, illustrated examples and a specialized table with the conversions according to the NEC.

If RPM has not been measured and logged in the VBOX file, the following guide can be used to generate an RPM channel. This theory is only applicable because the power accel test is only in one gear. Drive the test vehicle in the chosen acceleration gear and make a note of the exact speed at an exact RPM point, 54 km/h at 3000 RPM.

Speed, torque, power and efficiency of the motors are not constant values. Usually the manufacturer provides the following data in a table like this one (sample data from one of the motors used in generator kit): Also the manufacturers usually provide power curves for the motor at nominal voltage:

Output RPM formula = Input RPM times number of driving gear teeth divided by number of driven gear teeth. A small transmission in a mixer has a 12tooth gear on the motor shaft driving a 72tooth gear on the mixer blade. The motor is turning at 1,800 RPM. What is the mixer blade speed?

Up to 20,000 rpm Up to 12,000 rpm Up to 1700 rpm Up to 836 m / min Up to 1088 rpm Up to 580 rpm Up to 780 rpm Up to 1500 rpm Inverter operation Ex de: Up to 12,000 rpm Up to 7000 rpm Inverter operation

The product of the motor current and the applied voltage is the power input to the motor. At each point selected for calculation, the efficiency of the motor is the mechanical power output divided by the electrical power input. Once again, a sample table for motor M2232U12G is shown in Table 1. and a sample curve in Graph 1.

Special motor designs are required for nameplate voltages other than those listed in Tables 1 2. Motors greater than 100 horsepower rated less than 345 volts will not be furnished without approval of the Company. Motors with nameplate volt ages different than those listed in Tables 1 or 2 should be referred to the Company. DUAL VOLTAGE MOTORS
