This is a DC motor controller circuit, built using transistor TIP31 based on H-Bridge concept. The switch S1 and S2 are normally open , push to close, press button switches. The LED function is to indicate the direction of motor rotation, you may use any common LED type. The TIP31 transistors capable to handle 3A [...]
This is a circuit for DC motor circuit. This circuit is used PWM speed control using 555 timer IC. This is the figure of the circuit. The 555 Ic is wired as an astable and the frequency is constant and independent of the duty cycle, as the total resistance (R charge + R discharge, [...]
DMOS DRIVER FOR THREE-PHASE BRUSHLESS DC MOTOR. The L6235 is a DMOS Fully Integrated Three-Phase Motor Driver with Overcurrent Protection. Realized in MultiPower-BCD technology, the device
combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a three-phase BLDC motor including: a three-phase [...]
