DJI RoboMaster GM6020 Gimbal Motor
DJI RoboMaster GM6020 is a direct-drive brushless motor with a built-in driver, controlled over CAN or PWM. At 24 V it gives 1.2 N·m rated, 320 rpm no-load and 132 rpm at rated torque, with 0.741 N·m/A and 0.05° positioning accuracy. It has 10 pole pairs, an Ø18 mm hollow shaft and 3.5 kN dynamic radial bearing load. Ø66.7 × 42 mm, 468 g, XT30 power.

Guidance to help you shortlist. The basis is shown for each recommendation.
CAN-bus motor control
Built-in driver controlled over CAN (or PWM) with an on-board CAN termination switch — no separate ESC.
Manufacturer guidanceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.
