Product Description
Standard Hybrid Stepper Motors are a widely used type of stepper motor that combine the benefits of permanent magnet (PM) and variable reluctance (VR) stepper motors. They are known for their high precision, reliable performance, and moderate cost, making them ideal for applications where precise positioning is required without the complexity or cost of servomotors.
NEMA23 Standard Hybrid Stepper Motors series are standard 57mm*57mm size. 2 phase with 4 lead wires, 6wires and 3 phase with 3 lead wires. Suitable for medium power demand applications such as automation equipment, CNC machine tools, packaging machines, printing equipment, etc.
They can be mounted with 60mm diameter planetary gearbox to get more output torque.
A hybrid stepper motor typically features:
| Component | Description |
|---|---|
| Rotor | Made with permanent magnets and finely toothed poles. Usually has 50 teeth. |
| Stator | Contains multiple windings arranged in phases (usually 2 or 4). |
| Step Angle | Typically 1.8° per step (200 steps/revolution), but 0.9° and others are available. |
| Drive Type | Driven by a stepper driver that sends precise pulse signals. |
