Determining Electric Motor Load and Efficiency
1.15, running the motor continuously above rated load reduces efficiency and motor life. Never operate over-loaded when voltage is below nominal or when cooling is impaired by altitude, high ambient temperature, or dirty motor surfaces. If your operation uses
Crusher vibration problem | AMP Maintenance Forums
You should take a measurement and zoom in on 1X rpm. There will be a small difference in motor and crusher rpm, due to a few % slip on the belt. That way you can determine if the big 1X is from motor or from crusher. You should know that a high vibration on the motor could still come from a source in the crusher.
Squirrel Cage Induction Motor: Working Principle & …
· Squirrel Cage Induction Motor Working Principle. When a 3 phase supply is given to the stator winding it sets up a rotating magnetic field in space. This rotating magnetic field has a speed which is known as the synchronous speed. This rotating magnetic field induces the voltage in rotor bars and hence short-circuit currents start flowing in ...
