	The image to the right is a cross-sectional view of the inside of a hybrid bipolar stepper motor. As you can see, it has eight poles with six teeth each. This motor contains two coils- one wrapping the odd-numbered poles, and the other wrapping the even-numbered poles. The steel end-cap in the center of the image covers a cylindrical permanent magnet which surrounds the shaft.

Setting the Current Limit

	There are many factors that influence what the current limit should be set to. These include, but are not limited to,the acceleration and speed of the stepper, the supply voltage, applied torque, motor inductance, and coil resistance. The process of choosing the current limit can be simplified by following some general rules of thumb. The graphs in this section show a set of speed vs. current characteristics for the 3308 stepper with various power supplies.		There are many factors that influence what the current limit should be set to.

The process of choosing the current limit can be simplified by following some general rules of thumb. The graphs in this section show a set of speed vs. current characteristics for the 3308 stepper with various power supplies.

	In the these graphs, the '''“actual speed”''' of the motor is the maximum speed attainable in a real world test done with no load on the motor, but at very high acceleration. The '''“max speed”''' shows the limitation on speed imposed by the inductance of the motor coils at a given supply voltage~~. Given that the 1063 controller is only able to run at a maximum speed of 2048 full steps per second, our graphs don’t show data at higher speeds~~.

The '''“max speed”''' shows the limitation on speed imposed by the inductance of the motor coils at a given supply voltage.

	When the current limit is set low and the acceleration is high, the motor will not be able to provide enough power to accelerate itself and the load it’s driving. The motor also has to overcome friction losses within the system, and do work on the load - for example, lifting a weight. By increasing the current limit, more current and power is made available to accelerate and maintain maximum speeds. This can be seen on any of the graphs in the initial steep ramp of the actual speed. As the current limit increases, the motor is able to achieve higher speeds.
