How to calculate the power consumed by the motor?

1. The formula for calculating the rated power of the motor is as follows:

Rated power ≈ Rated torque * Rated speed * 0.105

For example 750 ≈ 2.39*3000*0.105

2. The formula for actual power consumption of the motor is as follows:

Power consumption = rated power * load percentage * rated speed percentage

For example, WD80M-07530S working in 1250rpm and 45% load torque percentage(U0-39)

then the power consumption = 0.75 * (1250/3000) * 45% = 0.1406 kW

Case1: When use VD2-014SA1G(standard WE80M-07530S) drive WE80M-10025S:

750 > 1000 * (actual speed/2500) * (actual torque/4)

So when run in 2500rpm, actual torque should < 3 N.m

     when run in 4 N.m, actual speed should < 1875 rpm

Case2: When use VD2-014SA1G(standard WD80M-07530S) drive WE130M-15025S:

750 > 1500 * (actual speed/2500) * (actual torque/6)

So when run in 2500rpm, actual torque should < 3 N.m

     when run in 6 N.m, actual speed should < 1250 rpm

Case3: When use VD2-014SA1P(standard WE80M-07530S) drive WE80M-12030S:

750 > 1200 * (actual speed/3000) * (actual torque/4)

So when run in 3000rpm, actual torque should < 2.5 N.m

     when run in 6 N.m, actual speed should < 1875 rpm
