Single IC chip Motor Driver for robots
A motor driver is required in pretty much all walkers including all of my CW series walkers. You need to use it any time you need to supply more current to the motors because the circuit can't supply enough. This...

The image shows a completed locked anti-phase motor controller built on a breadboard, utilizing general-purpose transistors to control small DC motors for robotics applications. A typical DC motor controller lacks a braking function, which is essential for precise control. Addressing...
Switching power supply circuit with STK6303
The T amplifier circuit schematic section is illustrated in Figure 3-51. It utilizes the Japan Sanyo STK6303 Pina, which is a high-power thick film integrated circuit. The maximum power supply voltage is 36V, and the output current can reach approximately...
Big Trak Motor Driver Schematic
Schematic of Big Trak's motor driver circuit. The toy includes 9112 and 9113 transistors (and sometimes 2N6715) because the 75494 chip cannot supply enough current to run the Big Trak's motors by itself.
The motor driver circuit for the Big Trak...
DC Drill Speed Controller Circuit
This DC drill speed controller circuit allows for the adjustment of the rotational speed of a drilling machine. A mini-drill machine is always...
This circuit utilizes a pulse-width modulation (PWM) technique to control the speed of a DC motor, which is...
DC motor armature series resistance start dynamic braking circuit of the two-way operation
The circuit illustrated in Figure 3-197 features a dish adjust rheostat (RP) that allows for the adjustment of field current, which in turn modifies the motor speed.
The circuit operates by utilizing a rheostat, which is a variable resistor that can...
Dc-motor-drive-with-fixed-speed-control
The NE5561 provides pulse-proportional drive and speed control based on DC tachometer feedback. This simple switching circuit consists of a 2N4920 PNP transistor with a commutation diode, which is used to deliver programmed pulse energy to the motor. A frequency...
DC Motor Reversing Circuit
A DC motor reversing circuit using non-latching push button switches. Relays control forward, stop, and reverse action, and the motor cannot be switched from forward to reverse unless the stop switch is pressed first.
The described circuit employs a system of...
Speed control for PCB drill
This circuit is designed for controlling the speed of DC-operated PCB drills. The core component of this circuit is the ICLM3578, an efficient integrated switching regulator suitable for such applications. The LM3578 features separate inverting and non-inverting feedback inputs (pin...
