• Lathe Modifiion: Variable Speed Treadmill DC Motor

    For an AC motor, you want something approaching 1HP on one of these lathes, and for DC would be ideal. Note that while my motor is rated at " HP", it is not an industrial rating and the motor probably makes closer to 1HP or a little more. Also note the speed range on the motor you're looking at. Most of these lathes get down close to 1:1 (usually 1:) on their pulley ...

  • Plant Engineering | Three steps to size motors

     · For motors that will use a variable frequency drive, ensure that the motor selected is a 3phase inverterdutyrated motor. Duty cycle of the load defines how much time the motor must run and stop. The motor's rated duty cycle must be better than that required by the load. Frequent starts are harder on a motor because they generate more heat. A motor with a duty cycle rating of less than .

  • How to Calculate the RPM of a Motor

    AC motors often have two or four poles but could also have more. The relationship between poles and the RPM of a motor has to do with the magnetic field produced in the stator poles. This field leads to the creation of magnetic fields in the rotor that relate to the frequency of the field in the stator. You also have to account for slip, which is the difference between the stator's ...

  • What's causing your high motor current?

     · This test consists of applying about 1/61/4 of rated AC voltage, or variable voltage up to a current value of 75%–125% of rated current, to two line leads of an induction motor while slowly turning the rotor manually. Use a clampon ammeter to measure any fluctuations in current. A current fluctuation greater than 3% for a used rotor or 1% maximum for a new rotor usually indies a broken ...
