Technical Advantage
Why Three-Phase Over Two-Phase Stepper Drivers?
Most competing bag machine drivers use conventional two-phase stepper technology. The three-phase hybrid architecture used in the HB-B3C / HB-B3HL delivers measurable performance improvements that directly impact bag quality and uptime:
Sine-Wave Current Control
Full-band sinusoidal output waveform — not trapezoidal — mimics AC servo motor current profiles, eliminating the micro-vibration that causes uneven bag lengths at high speed.
Ultra-Low Noise & Vibration
Three-phase winding geometry distributes electromagnetic force more evenly across the rotor. Result: quieter operation and less mechanical fatigue on feed rollers and cutting blades.
Higher Torque Density
Three-phase motors produce 40–60% more torque per frame size vs two-phase equivalents. The HB-B3HL variant pushes output current to 11A — exceeding standard 8A two-phase drivers.
Full Self-Protection Suite
Opto-coupler isolation between control and power circuits. Automatic shutdown on over-current, over-voltage, or overheating. NPN open-collector alarm output (VCEmax 15V, ICEmax 100mA).
Motor-Agnostic Drive Algorithm
Drive performance has minimal dependence on motor-specific parameters. Plug in any 90BYG, 110BYG, or 130BYG motor and the driver self-calibrates — no manual tuning of current tables required.
Flexible Micro-Stepping
Built-in micro-stepping subdivision supports standard and custom step-angle settings. Even at low subdivision, the internal interpolation achieves high-subdivision smoothness — critical for precision bag-length registration.

Installation Reference
Wiring & Signal Interface Guide
The following reference covers the two most common control-signal voltage scenarios. Always verify control voltage before wiring to avoid optocoupler damage.
// SCENARIO A — 12V Control Signal
Signal Common (COM)Direct to GND
Series ResistorNot Required
Internal Pull-up R1kΩ (built-in)
Min Pull-in Current≥ 8 mA
Logic LevelActive LOW
// SCENARIO B — 24V Control Signal
Series Resistor (per line)1kΩ (external)
Signal Common (COM)Direct to GND
Total Series R1k + 1k = 2kΩ
Min Pull-in Current≥ 8 mA
Logic LevelActive LOW
⚠ Each PUL/DIR/ENA signal line must have its own 1kΩ resistor when using 24V. Do not share a single resistor across multiple signals.
Alarm Output Wiring
The alarm output is NPN open-collector type. Connect a pull-up resistor (typically 4.7kΩ–10kΩ) between the alarm output pin and your PLC's 24V supply. Maximum collector-emitter voltage: VCEmax = 15V. Maximum collector current: ICEmax = 100mA.

Frequently Asked Questions
Technical FAQ — Three Phase Stepping Driver
What motors are compatible with this driver?
The HB-B3C and HB-B3HL are designed for all 90BYG, 110BYG, and 130BYG series three-phase hybrid stepper motors rated below 8A per phase. The HB-B3HL, with its 11A maximum output, also supports higher-torque variants in the 110BYG and 130BYG families that exceed the 8A limit of the original HB-B3C.
What is the difference between HB-B3C and HB-B3HL?
The HB-B3HL is the upgraded successor to the HB-B3C. Key differences: (1) The HB-B3HL uses an advanced Germany-sourced IGBT power module vs the Mitsubishi module in the HB-B3C. (2) Maximum output current is 11A vs 8A — providing higher torque and eliminating uneven bag-length issues at high production speeds. (3) The HB-B3HL adds an offline (FREE) WF control signal input not present on the HB-B3C. Both are direct form-fit-function replacements.
Can this driver work with my existing PLC running 24V control signals?
Yes. When using 24V control signals, you must add a 1kΩ resistor in series with each control signal line (PUL, DIR, ENA). The internal optocoupler already has a 1kΩ current-limiting resistor; the external 1kΩ brings the total to ~2kΩ, keeping signal current within safe limits while meeting the ≥8mA pull-in requirement. At 12V, connect directly — no external resistor needed.
Why does my bag machine produce uneven bag lengths? Can this driver fix it?
Uneven bag lengths at speed are almost always caused by motor vibration and resonance — a common problem with two-phase stepper drivers. The three-phase sinusoidal current control in the HB-B3C/HB-B3HL distributes electromagnetic torque more evenly, dramatically reducing resonance. The HB-B3HL specifically addresses this: its higher 11A output current increases motor holding torque, preventing position loss during rapid acceleration/deceleration cycles. If you're currently using a two-phase driver, upgrading to the HB-B3HL is the most effective single fix for inconsistent bag length.
What does the alarm output do and how do I connect it?
The alarm output activates when the driver detects an over-current, over-voltage, or overheating fault. It is an NPN open-collector output (VCEmax 15V, ICEmax 100mA). Connect a pull-up resistor (4.7kΩ recommended) between the alarm pin and your PLC's input supply. Under normal operation the output is pulled HIGH (no fault). On fault, it pulls LOW — wire this to a PLC digital input to stop the machine and trigger an alarm. This is critical for preventing motor damage in unattended production.
