The variable resistor remains a two-terminal device, so the arrow is just laid diagonally across the middle. A potentiometer is a three-terminal device, so the arrow becomes the third terminal (the wiper).

The same effect causes a slight decrease in torque with speed in the constant torque region as well. Finally, there is a rounding of the torque curve at the corner speed because the drive gradually transitions from being a current source to being a voltage source. The drive limits current to the motor below the corner speed and thus is a current source. Above the corner speed, the motor’s inductive reactance limits the current and the drive becomes a voltage source as it applies all of the power supply voltage to the motor.

Notice that a parallel-connected motor delivers performance identical to a series-connected motor running at twice the power supply voltage.

Note the location of each wire on both sides of the original connectors and identify them with markings before you cut off the old connector.

Use shrink wrap to encase the connections. This serves two purposes, one to insulate the terminal and the other is to add support to the end of the wire so that it will be less likely to bend and break.

Setting the current higher degrades the linearity of the motor and causes microstep bunching and attendant low-speed vibration.

We mentioned a catch, earlier. With these and other motor wiring variations possible, it’s easy to make a mistake. That drawing we said to follow could be wrong. Before you connect any wires, check the drawing carefully. That’s another reason to have that pocket motor wiring guide.
