This article discusses the process of controlling motor speed using various motor controllers. It explains that for motors up to 50A, there are several controllers available, but for higher current motors, only a few options exist. The article explores four different motor controllers and provides guidance on how to use them effectively. It emphasizes the importance of selecting a controller with a rating higher than the motor's typical operating current to prevent damage. The article also covers wiring instructions for different types of controllers, including those suitable for Arduino-based control. It details the setup for controlling motors with stall currents ranging from 5A to 20A, such as wheelchair motors. Additionally, it mentions the use of H-bridge-based motor controller boards for microcontroller interfacing and discusses the Alltrax 48300 controller designed for heavy-duty applications with high current requirements. The article also highlights the significance of incorporating external components like fuses, main contactors, diodes, and pre-charge resistors for safe and efficient motor control in high current applications.
