  • An introduction to electric motorsSTMicroelectronics

    The electric motor operation is based on the following points •At least one of the two magnetic field is generated by a solenoid carrying a current. •The phase relation between the rotor and stator magnetic field (i.e. the load angle) must be always greater than 0°in order to keep the motor in motion (negative angles reverse the rotation).

  • Impact Crusher Working Principle

    Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping

  • Determining Electric Motor Load and Efficiency

    Reasons to Determine Motor Loading Most electric motors are designed to run at 50 to 100 of rated load. Maximum efficiency is usually near 75 of rated load. Thus a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp peak efficiency is at 7.5 hp. A motor s efficiency tends to decrease dramatically below about 50 load.
