Hurst Manufacturing

All controllers are Discontinued by Hurst, for reference only

Hurst offers driver system components for 4-phase, unipolar stepping motors in several different configurations;
A DIP package for use as a component within a larger system
PC board sub-assemblies or stand-alone systems
A completely encased driver for stand-alone control

MODEL 220001

5V logic level control of:
Rotational direction
Single step (jog)
Phase driver disable

The 220001 is a DIP package containing all the basic circuitry required for operation of a 4-phase, unipolar stepping motor: a pulse generator, bi-directional logic sequencer, and phase drivers. It is fabricated as a thick film hybrid circuit using CMOS and bipolar components for small size and low power consumption.

NOTE: A SIP package is also available (Model 220006).
2-on, 2-off phase sequencing
Drivers rated at 500 ma per phase
Operation from single 6 to 24 VDC supply

The EPC-016 is a PC board assembly containing the 220001 hybrid, power drive transistors, and all external components needed for manual control of a stepping motor. A motor, DC power supply, and this board form a complete system.

4 Decade frequency/count display
Operation from a single 6 to 24 VDC supply
All control features of EPC-016
1 Amp per phase motor drive capability
Compact size: 1 " x 3.5" x 6"

The EPC-015 is a totally encased, hand-held driver containing al! the control features of the EK-016 plus selectable display of step frequency or step count. A motor, DC power supply, and this controller form a complete control system.

The EPC-013 is a PC board assembly with additional stepping motor control capabilities.

4 Decade counter/display
Manual count preset via BCD switches
Optional remote location of count preset switches and display
Manual or digital control of enable input
5V logic level output latch
Operation from 5VDC supply
Dimensions: 4.0" x 4.5"

The EPC-014 is a general purpose presettable counter/display PC board assembly suitable for use with most stepping motor drive systems. In a typical application, it is preset with a number of motor steps, counts and displays the steps as executed, and provides a control signal when the preset count is reached. It is also suitable for count and control applications using input pulses derived from sources other than step commands, e.g., from an external encoder or other sensor.
