By Control Method
Each control method offers different advantages and is suitable for specific applications depending on the requirements for precision, torque, efficiency, and smoothness of motion.
Wave Drive (One Phase On)
- Energizes one winding at a time, resulting in less torque as only one coil is active at a time.
- Simple applications where torque is not a critical factor.
Full Step Drive (Two Phases On)
- Energizes two windings to increase torque, moving the motor in full steps (1.8° or 200 steps/revolution).
- Applications requiring higher torque and simpler control.
Half Step Drive
- Alternates one and two phases, doubling steps (e.g., 400) for smoother motion and less vibration.
- Applications needing smoother motion without major torque loss.
Microstepping
- Microstepping divides steps into smaller increments like 1/2, 1/4, 1/8, and 1/16 by controlling motor current.
- Stepper driver microstepping used in CNC machines and 3D printers.
Current Control (Chopper Drive)
- Regulates motor current, reducing heat and boosting efficiency.
- Efficient motor operation applications often use microstepping.
Closed-Loop Control
- The closed-loop stepper driver uses encoder feedback for accurate and reliable motor positioning.
- Vital for precise positioning and reliability in robotics and automation.
Pulse Width Modulation Control
- The PWM driver adjusts duty cycle to precisely control speed and torque.
- Utilized in precise motor control for lab equipment and fine motion systems.
