motor, power factor also varies with load. The nameplate provides the power factor for the motor at full load. Active power is the power that does work; apparent power has a reactive component. This reactive component is undesirable the utility company must supply it, but it does no work. A power factor close to unity () is most desirable.

Oct 07, 2009· DC motors generally have a flat torque curve from max at zero rpm up to the base speed. Find a servo grade motor, these usually come with a tach, this gives very good speed control across the range. The KB and Baldor SCR and PWM drives found on ebay will drive a 90vdc or 180vdc direct off the 120v/240vac mains. Minder.

a motor has to do twice as much work per rotation which requires twice as much torque. That is why the shaft and frame of a 900 rpm motor are usually larger than those of an 1800 rpm motor of the same HP. When the speed of an AC motor is controlled by a VFD, HP or torque will change depending upon the change in frequency.

A 4pole motor is with 4 magnetic poles on the rotor and the number of related electromagnetic windings (circuits.) A 4pole motor has about ft.lbs of torque per horsepower where a 2pole motor has ft.lbs of torque. At 60 Hz, a 4pole motor is about 1800 rpm where a 2pole motor is 3600 rpm.

Sep 04, 2014· Hi all, Im wondering what would be a (somewhat simple) way to reduce the RPM on a motor. the motor is a 1/2hp or 3/4hp, and I need to bring it down to around 500 RPM for a piece of machinery I have. If I could do this internally with the motor, .

Mar 11, 2011· POWER (the rate of doing WORK) is dependent on TORQUE and RPM. TORQUE and RPM are the MEASURED quantities of engine output. POWER is CALCULATED from torque and RPM, by the following equation: HP = Torque x RPM ÷ 5252 (At the bottom of this page, the derivation of that equation is shown, for anyone interested.)

May 07, 2018· DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and rpm for DC fractional hp motors.
