[madcowswe] starts by pointing out that the entire premise of ODrive (an open-source brushless motor driver board) is to make use of inexpensive brushless motors in industrial-type applications. This ...

There are many products with built-in motors around us, such as air conditioners, vacuum cleaners, and electric fans. As robots, drones, and electric vehicles, which are expected to make a big change ...

[professor churlz] wrote in to let us know his results with modifying radio control ESCs (Electronic Speed Controllers) for use in a large (250lb range) BattleBot’s drivetrain. It’s a very long and ...

1. Field-oriented control (FOC), also known as vector control, maintains a constant stator field in quadrature with the rotor field irrespective of any bandwidth limitations presented by the PI ...

With the appropriate driver IC and microcontroller, designers can exploit the brushless motor's declining price, smaller size, lighter weight, and minimal maintenance. As recently as two years ago, ...

Just as fractional horsepower gearmotors freed factories in the 1920s from their cumbersome, inefficient, and unreliable overhead “networks” of shafts and pulleys connected by leather belts, today’s ...

After only a few years of being completely immersed in the culture of motor drivers, it is very easy for me to take for granted the fact that most people are not familiar with electromechanical ...
