DC Motor 5840-31ZY, with worm gear reducer, designed for applications that require high torque and a self-locking function. Due to its worm gear construction, the motor does not rotate backward when not powered, ensuring stability and safety in mechanical or robotic applications.
It offers a no-load speed of 80 RPM, low no-load current consumption of 0.3A, and a robust 8mm metal shaft, suitable for couplings, gears, or mechanical arms. The rotation direction is reversible by reversing the power polarity, and the high torque makes it suitable for lifting, opening, or actuation movements.
The motor can be controlled from an Arduino, STM32, ESP32 board, or other compatible platforms, through a motor driver (for example L298N or BTS7960), including speed adjustment via PWM.
