Note: This formula calculates both motor and pump- end efficiency as one total number. It is also called wire-to-water efficiency as it calculates the power input to the motor in relation to the power output from the pump. Do not compare this with the pump literature because the literature is for pump efficiency only.
erate the vehicle (EV weight is 1700 kg) from 0 km/h to 100km/h.2. Now you need to. the transmission gear (TG) ratio and calculate the torque:Example:Dif. rential ratio is approximately 3:1, TG ratio. 4:1. Therefore total ratio in the first gear is: = 3 ∗ 4 = 12For example, one EMRAX 22. motor can deliver 240 Nm peak torque and 120 Nm contin.

Basic Hydraulic Motor Calculations: Motor Torque (in lbs) = pressure (psi) x motor displacement (cu ins/rev) / 6.28. (Can also use horsepower (hp) x 63,025 / speed (rpm) Motor Speed (rpm) = 231 x flow rate (gpm) / motor displacement (cu ins/rev) Motor Horsepower (hp) = torque (in lbs) x motor speed (rpm) / 63,025.
Assuming that phase power PPH, phase voltage V1, and phase current I1 are measured and that friction-and-windage loss PFW has been obtained as shown in Figure 14, R0 and X0 can also be calculated for the motor from the no-load test data.
Even with energy-efficient motors, power factor is significantly affected by variations in load. A motor must be operated near its rated load in order to realize the benefits of a high power factor design.
Equation 6 – Bucket Elevator Power Formula – Friction Factor Method. Another way to account for the system friction is to add a multiplication factor to the calculated HP in Equation 3. This multiplication factor typically ranges from 10% to 30%, depending on the application. Consult your Bucket Elevator Supplier for additional information.
