40-14 G2 integrated motor and ESC module

The 40-14 G2 Module is an integrated motor and electronic speed controller for industrial small unmanned aircraft, made by Vertiq. It combines a brushless motor, a 30 A speed controller for up to six LiPo cells (6S) and an embedded rotor position sensor in a single unit, which is why it is listed as an electric motor with an integrated controller. It is designed for multirotor and other propeller-driven platforms in the industrial sUAS class, and the version listed here has a motor constant of 400 Kv.

The rotor position sensor and Vertiq's control algorithms allow closed-loop velocity control with tunable PID gains and feed-forward, and precise propeller positioning. The module is reversible in three dimensions, with no delay when it crosses zero speed, and it offers regenerative and active braking and active freewheeling. For an integrator these functions give faster thrust changes than a conventional sensorless motor and controller pair, which helps the flight controller keep stability in gusts and during aggressive manoeuvres, and reversible thrust is useful for specialised flight modes.

The base module measures 44.35 mm in diameter, with 38.76 mm from the bottom to the propeller face and 44.56 mm from the bottom to the top of the pin. The stator is 39.0 mm in diameter and 14.0 mm high. The base module weighs 154.4 g, and the maximum supply is 25.2 V, which corresponds to six LiPo cells. Because motor and controller share one housing, there is no separate controller to mount and no three-phase wiring between them, so the airframe wiring is reduced to power and a signal connection.

Communication with the flight controller uses DroneCAN, standard PWM or serial protocols, and the module is stated to work with common open-source flight controllers. Protection functions include over-current, over-voltage and over-temperature protection, with standard and custom telemetry, motor health monitoring and a safe arming procedure. The G2 design is modular, and add-ons such as covers to increase the IP rating, connectors for vehicle integration and LEDs can be fitted to the base module. Every module carries product tracking, which gives access to its serial ID, part number and calibration data, useful for inventory and quality records. Vertiq supplies a manual, tutorials and communication APIs, a datasheet, firmware and 2D drawings, and CAD models on request. The firmware is field-updatable, and the speed, servo and VSpin firmware styles are available.

Typical applications are the propulsion of industrial multirotors for inspection, mapping and delivery, as well as other small unmanned aircraft that need a compact propulsion unit with fast response and telemetry.
