3 Phase motor windings Resistance Calculations

Oct 27, 2010 · just curious,but why do you want to know? i would say the winding resistance of a 15kw motor would be close to zero while on small motors you would get much higher, if checking look for 3 very similar readings. cant think of a calculation other than R=P/I^2 but dont think that would work for 3 phase where P=SQ RT3*V*A*PF, so in summary, sorry

Calculations Simple Electric Motors

You may calculate the resistance of your motor by measuring the consumed current and applied voltage. For any given resistance (in the motors it is basically the resistance of the coil) this formula explains that the current can be controlled by applied voltage. The consumed electrical power of the motor is defined by the following formula: P

How to Measure Grinding Efficiency 911metallurgist.com

The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power

How to Calculate Motor Current With Winding Resistance

Apr 17, 2018 · You need to know both the length of the wire wrapped around a motor solenoid and the wire's diameter to calculate resistance. However, if you know the wire gauge, you know the diameter, because you can look it up in a table. Some tables help out even further by listing the resistance per standard length for wires of all gauges.
