Our Q2HB series driver for 2-phase hybrid stepper motor features high performance, low price, high response frequency and multi-level subdivision.

Q2HB44
The Q2HB44 full or half-step driver is designed for use with various 6 or 8-lead 2-phase hybrid stepping motors with the current below 4 A and the outside diameter from 12 to 40 V. It is widely used for small-sized CNC equipment, such as engraving machine, stripping machine, etc.

Features
1. The highest response frequency reaches 200kpps.
2. The coil current will be reduced by 50% when the pulse stops over 100 ms.
3. Bipolar constant current chopping mode is adopted.
4. There is optically isolated signal input or output.
5. The driving current is continuously adjustable from 0.5A/phase to 4A/phase.
6. The single power input voltage is from 12 to 24 V DC.

Q2HB44MA (B)
The Q2HB44MA (B) driver is an equal-angle constant-torque subdivision type product. Its driving voltage is 12 to 40 V DC. It is suitable for use with various 6 or 8-lead 2-phase hybrid stepper motors whose current is less than 4 A and outside diameter is 42 to 86 mm.

Our product adopts a special control circuit which enables the motor to run smoothly with noise reduced. This circuit improves the high-speed performance of the motor by 30% and reduces heat generation of the driver by 50%. This Q2HB44MA (B) drive is widely used for laser marking machines, laser engraving machines and other high-resolution, small-sized CNC equipment.

Features
1. This high-performance, low-price drive is set with 12/8-channel constant angle and constant torque subdivision. The highest subdivision is up to 200.
2. The highest response frequency is 200kpps.
3. The driving current can be adjusted continuously from 0.5A/phase to 4A/phase.
4. When the pulse stops over 100 ms, the coil current will be automatically halved.
5. The bipolar constant current chopping mode is adopted.
6. Optically isolated signal I/O is supported.

Q2HB88
With the input voltage of 18 to 80 V DC, the Q2HB88 full or half-step driver is suitable to drive various 6 or 8-lead two-phase hybrid stepper motors with the current less than 8 A and the outside diameter from 86 to 110 mm. It is widely used for engraving machines, medium-sized CNC machine tools, packaging machinery, and other equipment that doesn't require high resolution.

Features
1. This high-performance, low-price Q2HB88 driver can run at double 4 steps or four-phase 8 steps.
2. The driving current is adjustable from 0.5A/phase to 8A/phase.
3. When the pulse stops over 100ms,the coil current is automatically reduced to the set value.
4. The highest response frequency is up to 200kpps.
5. Bipolar constant current chopping mode is adopted.
6. Optically isolated signal input/output is supported.
7. There are over-voltage, overheat and over-current protection functions.
