Free electronic circuit design and schematic diagram
The schematic diagram below show 2-phase and 3-phase motor driver circuits. This circuit can used to drive an AC motor because this circuit has an integrated power operational amplifier, built-in power-output stage and high amplification factor. The needed AC signal is produced by the op amp that is configured as oscillator. The motor is driven by the high-current that is […]

In the circuit the rotary converter is nothing more than a second motor which is acting as a generator. The tools motor performed this function with the static converter, but at the cost of some loss of power. The idler motor is under no physical load but it cleans up the signal with the rotary converter. The only difference on […]

Capacitor have been use for decades to operate 3-phase motors on single-phase power. Two single-phase wires are connected to two of the inputs on a 3 phase motor on this method. Then, the capacitors is connected to one of the single -phase inputs and the third leg of the motor. Here is the schematic diagram of the circuit: The voltage […]

This motor driver circuit control the charging and power delivery cycles to enable small solar cell to drive dc motor. Here is the schematic diagram of the circuit: You have to make sure that 4700uF cap doesn’t leak, for more information about this solar cell dc motor driver circuit, you can see here.

This motor driver deliver the power form capacitor to the motor when the capacitor is charged to 1.75V by the solar cell. After powering the motor, capacitor voltage will be discharged and the circuit will cut the capacitor-motor connection when the voltage drops below 1V, allowing the capacitor to be charged to 1.75V again to repeat the cycles. The motor […]
