Cooperating with Basicmicro Motion Control, we created brushed BDC motor controllers for DIY robot kits. It was a variable DC motor controller with a switching voltage regulator. An important feature of the controller is that it can use both an open-loop and a closed-loop system.
In this method, the field winding is excited by a constant voltage but the armature winding is supplied with different voltages through switching devices. The speed of the motor will be proportional to the armature voltage.
Most FETs on the market have a built-in diode that performs this function, so in that case, an external diode provides extra protection. For resistive loads, such as LEDs or heaters, there is pelo need for additional protection since they have a straightforward linear relationship between voltage and current.
In my case, I chose to collect the required data manually. This is straightforward if you have a regulated power supply (RPS) or similar power supplies and a multimeter. Here is the data I collected:
OMDC-MD10P controllers are used with linear encoders for precise speed control in Omega's manufacturing process for metal sheath thermocouple wire.
Additionally, such gate drivers are not interchangeable. If they become discontinued, you’ll have to redesign the schematic together with the printed circuit board.
In this article, we’d like to share our own experience in the design and implementation of a brush DC motor controller. You’ll also learn about challenges you can meet if you decide to build it yourself.
Open-loop and closed-loop systems are fundamental concepts of control theory. Depending on the requirements or complexity of the electronic device, you can implement a control system either with or without feedback.

Strip the ends of the insulated wires or wrap the middle of the bare wires with tape. About one inch of exposed wire on each end is needed to get a solid connection. Using wire strippers to cut the correct diameter of the wire is easiest, but using scissors or a knife also works.
Settings can be one digit at a time or fast sweep. The OMDC-MD series speed control settings are exact and repeatable. It will precisely control speed to ±1/2 RPM of set speed, long term. No calibrations of the control are necessary.
In this tutorial, we’ll be discussing DC motor speed control with STM32 PWM and L293D H-bridge motor driver. I’ll also show you the DC_MOTOR library (driver) that I’ve developed for STM32 microcontrollers and discuss how it works and how it’s been built in this way. And we’ll create 3 different example projects with STM32 uC and DC motors.
After inserting the components we need to create the board outline and start arranging the components. The two capacitors should be placed as near as possible to the 555 Timer, while the other components can be placed wherever we want, but still in a logical arrangement according to the circuit schematic.
