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

Rated powerRated 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

3. When use VD2F-010SA1P(standard WD80M-04030S) drive WD80M-07530S:

In order to ensure the normal operation of the driver, the actual power consumption of the WD80M-07530S should be less than 400W

400 > 750 * (actual speed/3000) * (actual torque/2.39)
