40-14 G2 integrated motor and ESC module

The 40-14 G2 Module is an integrated motor and electronic speed controller (ESC) module for electric propulsion of industrial small unmanned aircraft, made by Vertiq. It combines a brushless motor, a 30 A ESC rated for 6S and an embedded rotor position sensor in one unit, so the motor and controller are matched and no separate ESC is mounted or wired.

Position sensing and the maker's calibration and control algorithms allow velocity control with tunable PID gains and feed-forward, field-estimated control, and precise propeller positioning. The module is reversible in three dimensions with no delay while crossing zero speed, supports regenerative and active braking and active freewheeling, and uses fast FET switching with gate drivers. For a multirotor designer this means quicker thrust response and the possibility of reverse thrust or controlled braking of the rotor, which improves attitude control and enables flight modes that a conventional sensorless motor and ESC pair handles less well.

The key figures are compact. The base module weighs 154.4 g. Its base dimensions are 44.35 mm in diameter, 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 supply is rated for up to six lithium polymer cells, 25.2 V, and the Kv option is 400. Because the controller is inside, the powertrain mass counted by the designer is this single figure.

Integration is through DroneCAN, standard PWM or serial communication. Compatible flight controllers include ArduPilot, PX4 and Betaflight. Protection covers over-current, over-voltage and over-temperature, with standard and custom telemetry, motor health monitoring and a safe arming procedure. The design is modular, so the user can increase the IP rating, customize the vehicle integration and add LEDs. Documentation includes a manual, tutorials, communication APIs, a datasheet with 2D drawings, a CAD model on request, thrust data and firmware releases.

Typical applications are multirotor and VTOL propulsion on industrial small unmanned aircraft, where the combination of a 6S supply and a compact motor and controller in one body suits quadcopters and similar airframes in inspection, mapping and delivery roles.
