NettetAnother method through which we can perform DC motor speed control is the flux control method. From the equation of speed, we see that the speed of the dc motor is inversely proportional to the flux per pole. Hence if we increase flux the speed will decrease or vice versa. To control flux, we add a rheostat with field windings in series. Nettet4. mai 2016 · 11. The number of poles is the number of magnetic cycles in one revolution of the shaft. When setting up for driving a BLDC, it's useful to step thru the drive phases one by one manually. I usually mark a point of the shaft, then add a sticker or something on the stator to record where the shaft is.

Nettet17. jun. 2016 · If the motor has only two poles, that rotor pole moves back to the original position during the next half cycle. So there is one revolution per cycle of the power frequency. If there are more than two poles, the rotor moves from one pair of poles to another pair of poles during one cycle of the power frequency. Thus Speed(RPM) = … NettetThe synchronous speed of an AC motor is determined by the frequency of the source …

Nettet29. apr. 2024 · I find it simplest to define speed in radians/sec, voltage in volts rms line-to-line, torque in Nm, and current in amps rms. Note that dimensionally, Ke and Kt are the same: volts / rad/s is equivalent to Nm / amp. Using these units, Kt = Ke * sqrt(3) for a three-phase motor. For your motor then: 464.52 rpm is 48.64 rad/s.
