Nettet21. apr. 2024 · In the AWG system, the higher the number of the cable rating, the thinner the wire and, therefore, the less current it can carry. For example, if you look at the … NettetHorsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. = 472V x 20A x 0.90 x 0.85 x 1.73/746 = 17 Hp. The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation.

Nettet15. nov. 2024 · To determine motor performance, establish the following three factors: Motor speed. Motor torque. Moment of inertia. Once the above three factors are calculated, the motor will be selected depending on the values obtained for speed, inertia, and torque. A range of of motors exists to choose from, such as servo, AC, stepper, … NettetMotor Winding Material #3: Silver. Wires made of silver offer greater electrical conductivity than copper and aluminum winding wires. However, silver wires don’t come off the line cheap: the cost of a silver wire is substantially higher than an equivalent copper or aluminum wire. Motor Winding Material #4: Carbon Nanotubes NettetIn order to determine the performance you'll need from the motor, there are three factors to calculate; Moment of Inertia, Torque and Speed. (Refer to the below sections on calculations for each.) Once you've calculated the inertia, torque and speed for the motor you'll select the type of motor based on the required specifications. homefinder whitby
