Description

The DYS D3542-4 brushless motor is designed for pilots building efficient, powerful multirotors for long-range flight, aerial photography, and medium-duty payload carrying. Its 1450KV winding is perfectly matched with large-diameter propellers (10-12 inches) on 3S or 4S battery packs, generating substantial thrust while maintaining excellent efficiency for extended flight times.

Built with a durable steel housing and a substantial 5mm shaft, this motor handles the inertial loads of large props with stability. The 35mm stator diameter and 42mm stack height provide the magnetic volume necessary for high torque output, translating to responsive throttle control and reliable performance across its 7.4V to 15V operating range. Its 130g weight represents a solid, performance-oriented build quality suited for professional-grade UAVs.

Key Features

High-Torque 35x42mm Stator: Delivers powerful and efficient thrust for medium to large multirotor frames.
Pre-Soldered 3mm Bullet Connectors: Enables quick, solder-free installation and secure electrical connection with compatible ESCs.
Durable Steel Construction: Withstands vibration, heat, and mechanical stress encountered in prolonged and demanding flight operations.
Optimized 1450KV Winding: Ideal for pairing with 10-12 inch propellers on 3S-4S LiPo systems, balancing speed and torque for endurance flying.
5.0mm Precision Shaft: Provides a robust and wobble-free mounting point for large, high-pitch propellers.
High Power Handling: Capable of up to 690W input power, supporting aggressive throttle maneuvers and heavy-lift scenarios.

Applications

Long-range FPV and mapping drones utilizing 10-12 inch propellers.
Heavy-lift quadcopters and hexacopters for aerial photography and light payload delivery.
Medium-sized agricultural or monitoring UAVs requiring efficient, high-torque propulsion.
Custom-built multirotors for endurance racing or search-and-rescue platforms.
Scale RC airplane conversions requiring a reliable, high-power brushless motor.

Frequently Asked Questions

What is the recommended propeller size for the DYS D3542-4 1450KV motor?

The DYS D3542-4 1450KV motor is optimized for large-diameter propellers, typically in the 10-inch to 12-inch range. On a 3S LiPo battery, a 10x5 or 11x4.7 propeller is ideal for efficient thrust. When using a 4S pack, a 10x4.5 or 11x4.5 propeller will provide excellent performance without overloading the motor or ESC.

What ESC is required to run this motor safely?

A 70A Electronic Speed Controller (ESC) is the recommended minimum for the DYS D3542-4 motor. For optimal performance and headroom, especially when using 4S batteries and large props, selecting an ESC rated for 80A or higher is advisable. Ensure the ESC firmware (e.g., BLHeli_S, BLHeli_32) supports the current and timing requirements of this high-torque motor.

Does this motor come with connectors installed?

Yes, the DYS D3542-4 motor comes with pre-soldered 3mm male bullet connectors. This allows for direct, solder-free plug-and-play connection with ESCs that have corresponding 3mm female bullet connectors, simplifying the build process and ensuring a reliable electrical interface.

What is the maximum voltage and cell count for this motor?

The DYS D3542-4 motor has an operating voltage range of 7.4V to 15V. This corresponds to 2S (7.4V), 3S (11.1V), and 4S (14.8V) LiPo battery configurations. It is not recommended for use with 5S or 6S packs, as exceeding the 15V maximum will risk damaging the motor windings and insulation.
