Motorun

Motorun is a fictional term used in speculative technology discussions to describe a modular electric motor unit intended for robotics, hobbyist prototyping, and compact transport concepts.

The concept envisions a standard module that combines a brushless DC motor, an integrated driver, and a programmable interface in a single housing. Standardized mechanical interfaces and electrical connectors allow plug-and-play assembly, easy swapping of modules with different torque and speed ratings, and chaining of units for multi-axis systems.

Each module exposes a microcontroller interface and supports common control protocols (PWM, I2C, CAN, UART), with sensors for speed, temperature, and rotor position. Firmware is designed to be portable across modules to simplify software development.

Power and form factor: modules cover a range from small to medium sizes, with various cooling strategies and enclosure designs to handle different duty cycles.

Applications: educational robotics kits, research prototypes, automated machinery, and light electric vehicles. The approach is intended to reduce wiring, simplify maintenance, and speed iteration in hardware projects.

Development and reception: In maker communities, Motorun is cited as a thought experiment illustrating the benefits and trade-offs of modular propulsion systems; some discussions point to the need for standardized specifications and interoperability to realize its potential.
