The design and functionality of a DC motor controller depend on the characteristics of
the motor and the electronic system it powers. Using the example of a brushed DC
motor controller, we'll consider its operating principles and circuit design.
If you are working on a project that calls for an electric motor unit, you will certainly have come across the terms IP65, IP67 and IP68. What do these protection ratings cover? Which protection should be chosen based on your project? Here's a brief answer to these questions.
The extensive collection with illustrations and descriptions includes formulas, terminology and explanations of the calculations that are relevant for drive systems. A flow chart provides assistance in selecting the right drive for each purpose.
If the duty is continuous, that means the motor, if properly sized, will reach thermal equilibrium typically in about 20 Minutes of continual operation (possibly more, depending on the size of the unit).
A traditional gantry system employs X-Y or X-Y-Z range of motion. Mounted on a base plate, usually granite, 2 parallel rails constitute the synchronized Y axis motion while the cross axis (bridge axis) provides the X motion. A vertical axis can be added on the bridge for the Z motion.
A Split Bridge system can be less complex than a traditional gantry system because synchronization of the two parallel linear motors is not required. Both systems are used in industrial production, testing, and additive manufacturing.
