High Torque Nema 23 Stepper Motor 8-Wire Bi-Polar/Uni-Polar- Suzhou Retek Electric Technology Co., Ltd.

8-Wire NEMA 23 Stepper: Maximum Winding Flexibility

The 8-Wire NEMA 23 Stepper Motor is the most versatile configuration, featuring all four ends of the two independent motor windings brought out to the connection terminals.

This provides maximum flexibility for the user to configure the motor to achieve different performance characteristics: 1) Series Connection (Max Torque): Highest inductance, high resistance, highest torque at low speeds. 2) Parallel Connection (Max Speed): Lowest inductance, low resistance, best torque at high speeds. 3) Half-Coil (Uni-polar): Simplest drive, but lowest torque. The 8-wire motor allows system designers to precisely tune the motor's electrical time constant to match their application's speed/torque profile.

Introduction

Detailed Parameters and Performance Data

RETEK: Versatility for Performance Optimization

Suzhou Retek Electric Technology Co., Ltd. provides the 8-wire NEMA 23 series for engineers who need to extract every ounce of performance from their stepper system. We provide detailed data for all three wiring configurations, allowing the user to select the optimal setup for either maximizing acceleration (parallel) or maximizing static holding force (series).

Applications

Advanced Technology Highlights

Advanced Configuration Applications for 8-Wire Steppers

CNC Routers and Mills: Motors where the X and Y axes might require high-speed (parallel) while the Z axis might require high holding torque (series). Challenge: Optimizing different axes on the same machine.
Automated Assembly Lines: Drives for indexing tables where initial startup may be slow (high torque), but continuous operation is fast.
Laser Engravers: Balancing high-resolution positioning (low speed) with fast travel moves (high speed).
Custom Test Rigs: Systems where the required speed/torque changes depending on the test profile.

Service & Support

Technical Advantages and Core Design Features

Maximum Configuration Flexibility: Allows optimization for low-speed torque or high-speed performance via wiring changes.
Uni-polar Compatibility: Can be driven by simpler, older uni-polar controllers if required (using 5 or 6 wires).
Inventory Reduction: A single motor part number can cover three distinct performance profiles.
High Torque and Resolution: Retains the core benefits of the hybrid stepper design (1.8∘ step).
Lower Inductance Options: Parallel wiring drastically lowers the inductance, allowing the current to build faster, enhancing high-speed performance.

Frequently Asked Questions

Common Inquiries Regarding 8-Wire Steppers

Q: If I use the series connection, do I need a higher voltage driver?
A: Yes. The series connection doubles the inductance and resistance. To maintain the same high-speed torque, you must compensate with a higher drive voltage to overcome the increased electrical time constant.

Q: Why does the parallel connection give better high-speed torque?
A: Parallel wiring halves the inductance. Lower inductance means the current rises and falls faster (lower electrical time constant), allowing the motor to draw full current more quickly, even at high step rates, thus maintaining torque.

Q: Which wires are the coil ends?
A: The 8-wire standard separates the four wire pairs: (A, A'), (B, B'), (C, C'), and (D, D'). The C and D pairs are often the center taps (if applicable). For Bi-polar, you connect A to C and B to D, etc., to achieve series/parallel.
