We can purchase DC motors with or without brushes with ac tachometer outputs already provided by the manufacturer. A very low cost speed control can be constructed with these motors in combination with the LM2907. The most simple version is … Continue reading →

The following figure show us an alternative approach which gives proportional control. The charge pump integrator is shown in a feedback connection around the operational amplifier. For zero speed, the output voltage is equal to the reference voltage set up … Continue reading →

The other name of split phase motor is an induction start/induction run motor. This motor has two windings : a start and a main winding. The start winding is made with fewer turns and smaller gauge, relative to the main … Continue reading →
