Are Stepper Motors AC or DC?
Fundamentally, stepper motors are designed to operate on direct current (DC). Although the current pattern within their internal windings might resemble alternating current, their power source and control mechanism are entirely DC-based. This creates a fundamental distinction from AC motors, which connect directly to an...
