Modul control viteză motor PWM 5A 90W

Product Description

This module is a compact controller for adjusting DC motor speed via PWM. The NE555-based generator provides smooth speed control using the built-in potentiometer with switch, while the D4184 power MOSFET ensures efficient load switching. Connections are made quickly through the screw terminal (power input and motor output), with no soldering required. An LED indicates when the module is powered. It’s suitable for prototypes, models, fans, micro-pumps, and hobby applications where simple and robust speed control is needed.

Technical Details

• Control method: NE555-based PWM (continuous duty-cycle adjustment).
• Power stage: D4184 N-channel MOSFET.
• Supply voltage: typically 5–35 VDC (depending on the motor’s rated voltage).
• Maximum current: limited by the MOSFET, PCB traces, and cooling; recommended for small/medium DC motors.
• Adjustment: potentiometer with ON/OFF switch.
• Motor protection: fast freewheeling diode on the output.
• Connections: 4-position terminal block (VIN+, VIN−, M+, M−).
• Indicator: “Power” LED.
• Use case: speed control; does not reverse direction (reversal requires an external solution).
• Notes: for reliability, keep margin to voltage/current limits and ensure ventilation under high loads.
