Complete Stepper Motor Control Using the UCN4202 (MEC165E)

This shield circuit is adapted from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. It can be used as a shield for stepper motors in mechatronics or robotics projects or as a building block for more simple projects.

The UCN4202 (Sprague) is another IC that contains all the functions required by a complete stepper motor control. This IC is used in a basic configuration as shown by Figure 1.

Driving Stepper Motors with the MC1413/MC1416 (MEC163E)

This shield circuit is adapted from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. It can be used as a shield for stepper motors in mechatronics or robotics projects or as a building block for more simple projects.

The MC1413 and MC1416 ICs, from Motorola, are equivalent to the ULC2003 and can be used to drive stepper motors as shown in Figure 1. The MC1413 has an equivalent circuit for each stage, and the MC1416 has the other configuration.

Driving a Stepper Motor with the ULN2002 and ULN2003 (MEC162E)

This circuit is adapted from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. It can be used as a shield for stepper motors in mechatronics or robotics projects or as a building block for more simple projects.

Stepper motors with current requirements up to 500 mA can be driven directly from ICs of the ULN200X series. These ICs are formed by paired power transistors, including the base resistor and the diode to protect them against the voltage spikes generated when the windings of the stepper motor are switched on and off.

Step-by-Step Generator (MEC161E)

This circuit is adapted from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. It can be used as a control shield for stepper motors in mechatronics or robotics projects or as a building block for simple projects. Stepper motors can be controlled directly from a switch placed at the input of a translator. As each pulse is produced when the switch is closed, the motor will advance one step.

Step Generator Using the 4093 (MEC160E)

This circuit is part of my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. It can be used as a control shield for stepper motors in mechatronics or robotics projects or as a building block for simple projects. A step generator is shown in Figure 1. This circuit uses a CMOS IC and can drive translators of the same logic type.
