Bipolar Motors
This section shows some bipolar motors which were used.
products. In each case, the wiring is:
They only work on the BiStep
Jameco 117954 5 Volt, 0.8 Amp, 7.5 deg/step
This unit is an Airpax LB82773-M1 2 phase bipolar stepping motor. 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:
