When working with motors that need to change direction, such as in robotic arms, it is essential to ensure secure operation. One common method to achieve this is by using bi-directional motor relays. Relays act as solenoid-driven contacts that can manage large load currents involved in motor operation while allowing logic-level inputs to manage the direction changes.
To begin, you need dual-channel switching relays: one for clockwise motion and one for رله reverse run. These should be selected based on full-load amperage. The motor has a pair of armature connections, and reversing the voltage polarity across these terminals changes the direction of rotation. The relays are wired in such a way that when the FWD coil receives power, it connects the power supply to the motor in the forward direction, and when the REV relay engages, it reverses the current path.
