Many motors offer a quadrature encoder that give feedback on whether, and in which direction, the motor shaft is moving. But if you’re clever about analyzing the data you can use a quadrature encoder ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

This application note describes the Quadrature Encoder peripheral on the Z32F128 device and provides two examples of peripheral usage. The quadrature encoder decodes the signals received from an ...

The counter project was created to read one or two digital or analog sensors and display the running total on an organic LED display. The speed of an attached DC motor can be controlled by the counter ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...

Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square waves, offset by 90° in phase. The number of ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

The leading and longest established online Process Engineering publication serving the Process Manufacturing Industries ...

If you are a novice to rotary encoders for human-machine interface, there is a potential pit-fall. Otherwise called quadrature encoders, they deliver two-bit gray-scale binary on rotation, with the ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...
