Motor Wiring Examples

The systems have been tested with an interesting mix of stepper motors, both unipolar and bipolar. All were purchased from Jameco (www.jameco.com). The following sections summarize some of the motors tested.

The wiring diagrams and tables shown are identical for the 6 wire connectors on the BS1010 and SS1010

The current regulating products (the BCxxx series) strictly support 4 wire bipolar motors.  The connector pinouts match the inner 4 connections on the 6 wire connectors of the BS1010 and SS1010 units.

The motors covered by this document are as follows: note that there are more details available for these and other motors in the manuals relating to the particular controller.

Unipolar Motors Bipolar Motors

Unipolar Motors

This section shows some unipolar motors which were used.   They work on the SS1010 and BS1010 series of boards; in most cases that use 6 wires, they can also be made to work on the BCxxxx series by not connecting the "COMMON" leads.  Motors that have 5 leads may only be operated by theSS1010 and BS1010 products.

In each case, the wiring is:


Jameco 105873 12 Volt, 0.150 Amp/winding, 3.6 deg/step

This Howard Industries stepping motor has a manufacturing part number of 1-19-4202. It is wired as:

This Airpax motor has a manufacturing part number of C42M048A04.  As with the other Airpax motor, it does not microstep at all. Mode "3o" can smooth its actions, but it does not "stop" at any other points than ½ step locations. It is wired as:

When using a 5 volt motor (such as this), you may use a single, 7.5 volt power supply (this may slightly over-voltage the motor), or you may use a split supply. In this case, use a 7.5-12 volt supply for the power to the digital electronics (pins 1 and 4 on the power connector), and a 6 to 7 volt power supply for the motor (pins 2 and 3 on the power connector). The TI driver chips being used drop 1.1 to 2 volts (depending on the chip and the temperature); accordingly, cooling the board becomes quite important, in order to have stable drive voltages for the motor.


Jameco 155432 12 Volt, 0.4 Amp/winding, 2000 g-cm, 1.8 deg/step

This motor provides for 2000 g-cm of holding torque, and has a manufacturing number of GBM 42BYG228. Its wiring order is:

This excellent motor has a manufacturing part number of STP-57D317. It uses 6 wires, with the wiring being:

Jameco 173180 12 Volt, 0.060 Amp/winding, 0.09 deg/step geared

This tiny motor has a manufacturing part number of 30BYJ02AH, BF33. Thanks to its gearing, it claims to have both a holding and detent torque of 400 g-cm! It uses 5 wires, already in a connector which directly works with our product. However, two of the wires must be switched (i.e., the order of the wires is incorrect for our use): the pink and yellow wires need to be reversed in the connector. The correct order therefore becomes:

Bipolar Motors

This section shows some bipolar motors which were used. In each case, the wiring is:


Jameco 117954 5 Volt, 0.8 Amp, 7.5 deg/step

This unit is an Airpax LB82773-M1 2 phase bipolar stepping motor. Its wiring, as it arrives, actually works (if you plug its 4-wire connector into the 4 non-ground pins on the controller).  This motor does NOT microstep at all. It may only be used in full and half step modes (i.e. use the configuration commands "0o", "1o" and "2o")! Mode "o3" may smooth its steps slightly, but it will not really stop at any other than ½ step locations.

When using a 5 volt motor (such as this), you may use a single, 7.5 volt power supply (this may slightly over-voltage the motor), or you may use a split supply. In this case, use a 7.5-12 volt supply for the power to the digital electronics (pins 1 and 4 on the power connector), and a 6 to 7 volt power supply for the motor (pins 2 and 3 on the power connector). The TI driver chips being used drop 1.1 to 2 volts (depending on the chip and the temperature); accordingly, cooling the board becomes quite important, in order to have stable drive voltages for the motor.

The wiring of this unit is therefore:

Jameco 168831 12 Volt, 1.25 Amp

This motor only works with our 2 amp products, such as our BC2D20, BC4E20 and BC6D20 series. It is a Superior Electric "SLO-SYN" stepping motor, model number SM-200-0050-HL. We ordered it since it stated "1 amp"; however, it turns out to be a 1.25 amp product, and therefore will cause the one amp product (the BS1010) to overheat (and probably fail) after just a short period of use, if it is configured to run two of the motors at a given time. We tested it with the wiring of:

If you fail to wire the unit correctly, you will be shorting power to ground, and are likely to burn up the board!  This is not a warranted failure!
