The SIYI E6 combines a motor and an FOC electronic speed controller in an integrated propulsion unit. It is aimed at civilian industrial and agricultural UAV frames where a coordinated motor, controller and propeller arrangement is useful. The catalog identifies a 155KV motor, a 30mm arm fit and a 24 × 9-inch propeller.
Those physical details give a clearer comparison than a maximum-thrust number on its own. Start with the arm and mounting arrangement already present on the aircraft, then compare the required control connection, available power supply and the exact propeller option offered with the unit.

E6 documentation describes PWM and CAN throttle support, with CAN listed as the communication protocol. The product also includes data monitoring and fault-storage functions. If those functions are important to the buyer, identify the receiving flight controller and the information needed by its operator or maintenance team.
A CAN connection on two pieces of equipment is not, by itself, proof that every telemetry field or software feature will work between them. Ask the supplier to identify the supported combination and the relevant product revision, keeping the requested monitoring functions visible on the quotation.
| Selection point | Catalog reference |
|---|---|
| Arm interface | 30mm fit; compare the actual mount and available space. |
| Propeller | 24 × 9-inch carbon-fiber nylon composite. |
| Propulsion-unit mass | 715g without the propeller. |
| Propeller mass | 109.6g, listed separately. |
The separation between unit and propeller mass helps when replacing an existing motor/ESC assembly. Keep any additional mounting adapters, leads or frame parts in the aircraft's own mass allowance instead of assuming that the tabulated unit figure covers them.
The supplied catalog recommends 12–14S LiHV and states a 63V maximum working voltage. The battery chemistry and voltage limit should stay attached to the offered revision, particularly when comparing supplies already used by a fleet. They should not be silently changed to a different chemistry or voltage class.
The manufacturer lists 12.5kg maximum thrust per axis and a recommended per-axis takeoff-weight band of 3–6kg. These describe the propulsion selection, not an aircraft payload allowance. Similarly, the listed IPX6 code should not be expanded into a dust rating or an unrestricted weather guarantee for the finished drone.

Provide the arm dimensions, current motor markings if replacing a unit, the intended power source and flight-controller model. Ask for the propeller choice, mounting hardware and lead arrangement to be specified. For a maintenance purchase, distinguish complete units from spare propellers and individual components.
No. The supplied table excludes the propeller from that unit figure and lists 109.6g separately for the propeller.
No. It is a maximum single-axis thrust specification. The finished aircraft needs its own complete mass and operating assessment.
No. Arm fit, propeller dimensions, supply voltage, controller connection and the offered assembly all matter when comparing propulsion units.
