RPM stands for revolutions per minute. This is calculated for different devices and can indicate how fast something is going. For a DC motor, the RPM is calculated by how many times the motor turns.
A 2-Pole motor runs twice as fast as a 4-pole motor. The 2-pole motor has 2 windings at 180 degrees apart and the four pole motor has four windings at 90 degrees apart. The rotor tries to move from pole to pole with each half cycle of the AC current so the motor no-load speed for 60 cycle current is 2x3600/#poles. This is 1800 rpm for a 4-cycle motor and 3600 rpm for a 2-pole motor.
there is two winding is there, one for slow speed , another for fast speed, but both are not variable, but is constant speed. If you use inverter, High speed wingding used for inverter connection .
what size motor
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
Speed
as fast as you want it too go
about 17-25 mph (weight dependent)
what part of a cup is 30cc?
30cc in mililitre is 30
3/10 of 100cc. Also, since 1cc=1mL, 30cc=30mL which is 30% of 100mL or 3% of 1000mL. Since 1000mL=1 Liter, 30cc=.03Liter. Had enough of this?
30cc
fast...very fast.
30 gram
you can find this in india.
Yeah.
420 cc how fast
