1. Uvod
This manual provides detailed instructions for the installation, operation, and maintenance of the DollaTek 1803BW DC PWM Motor Speed Controller. This compact and efficient module is designed to control the speed of low-voltage DC motors by adjusting the Pulse Width Modulation (PWM) signal. It is suitable for various applications requiring precise motor speed regulation.
2. Karakteristike
- PWM Speed Control: Controls DC motor speed by adjusting the Pulse Width Modulation.
- Wide Voltage Raspon: Compatible with input voltages from 1.8V DC to 15V DC.
- Trenutni kapacitet: Supports currents up to 2 Amperes.
- Zaštita od prekomjerne struje: Integrated 2A fuse provides protection against excessive current. The fuse is designed to reset automatically once cooled after an overcurrent event.
- Kompaktan dizajn: Small dimensions (32 x 32 x 14 mm) for easy integration into projects.
- External Potentiometer Connection: Designed for connection with an external potentiometer for speed adjustment (potentiometer not included with the module itself, but shown in some product images as an example of use).

- If the module shows signs of damage or malfunction, discontinue use immediately.
6. Postavljanje i instalacija
The DollaTek 1803BW controller features clear markings for power input and motor output connections. Refer to the diagrams below for proper wiring.
Slika 6.1: Top view of the controller module, highlighting the main components and connection points.
Slika 6.2: Dno view of the controller module, indicating the power input and motor output solder pads. The labels 'Power+' and 'Power-' are for the DC power supply, and 'Motor+' and 'Motor-' are for the DC motor connections.
6.1 Ožičenje
- Ulazna snaga: Connect your DC power supply (1.8V to 15V) to the terminals labeled "Power+" and "Power-". Ensure correct polarity.
- Izlaz motora: Connect your DC motor to the terminals labeled "Motor+" and "Motor-". The polarity for the motor connections will determine the direction of rotation.
- Priključak potenciometra: The module includes a 3-pin header for connecting an external potentiometer (typically 10KΩ linear taper). Connect the potentiometer's outer pins to the module's outer pins on the 3-pin header, and the potentiometer's wiper (middle pin) to the module's middle pin.
Slika 6.3: Example of the controller module connected to an external potentiometer for speed adjustment. The potentiometer allows for variable resistance to control the PWM signal.
6.2 Montaža
The module has four mounting holes in its corners, allowing it to be securely fastened to a project enclosure or PCB using small screws (not included).
Slika 6.4: Dimensions of the controller module, showing its compact size and the location of mounting holes.
7. Uputstvo za upotrebu
- Uključeno: After ensuring all connections are correct and secure, apply power to the "Power+" and "Power-" terminals.
- Podesite brzinu: Use the connected external potentiometer to adjust the motor speed. Turning the potentiometer knob will vary the PWM duty cycle, thereby changing the average voltage supplied to the motor and controlling its speed.
- Iskljuciti: To stop the motor and power down the module, disconnect the main DC power supply.
Note: This module does not include an on/off switch. Power control must be managed externally.
8. Održavanje
- Održavajte modul čistim i bez prašine i ostataka.
- Periodically check all connections for tightness and ensure there are no loose wires.
- Avoid physical impact or excessive force on the module.
- If the resettable fuse trips due to overcurrent, disconnect power, identify and resolve the cause of the overcurrent, and allow the fuse to cool and reset before reapplying power.
9. Otkrivanje problema
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Motor ne radi. | No power, incorrect wiring, faulty motor, potentiometer at minimum setting. | Check power supply, verify all connections, test motor independently, adjust potentiometer. |
| Motor runs at full speed regardless of potentiometer. | Potentiometer not connected correctly or faulty. | Ensure potentiometer is wired correctly (3 pins), test potentiometer. |
| Motor runs intermittently or stops. | Loose connections, overcurrent protection triggered, insufficient power supply. | Check all wiring, reduce motor load, ensure power supply can deliver sufficient current. Allow fuse to reset if tripped. |
| Module gets excessively hot. | Overload, short circuit, operating outside specifications. | Reduce motor load, check for short circuits, ensure input voltage and current are within limits. |
