motorcomputer

A motorcomputer, sometimes referred to as a motor control computer, is an embedded computing device designed to manage and supervise electric motors within automated systems. It combines real-time data processing with control algorithms to regulate motor speed, torque, and position, while coordinating with power electronics and safety functions.

Typical architecture includes a microcontroller or digital signal processor (DSP) or system-on-chip (SoC), memory, input/output interfaces, and software. It interfaces with sensors (rotor position encoders, resolvers, Hall effect sensors, current and voltage sensors) and with motor drives such as inverters or servo drives. Many motorcomputers run a real-time operating system and implement feedback control loops at high sampling rates.

Common control methods include proportional-integral-derivative (PID) controllers, field-oriented control (FOC) for AC motors, and vector control, as well as trajectory planning for motion profiles. Protection features monitor overcurrent, overtemperature, short circuits, and motor stall, and can initiate safe shutdowns or faults reporting.

Communications and integration: interfaces such as CAN, EtherCAT, Modbus, ProfiBus, Ethernet/IP, and USB enable coordination with PLCs, HMIs, and other automation components. Applications span industrial automation, robotics, CNC machines, electric vehicles, and aerospace actuators.

History and scope: motorcontrol has evolved from analog controllers to full embedded systems; modern motorcomputers emphasize real-time performance, safety, and integration with digital automation ecosystems.
