Frequently Asked Questions

What is the compatible battery range for the T-Motor MN501-S 300KV motor?

The MN501-S 300KV motor is designed for 6S to 8S LiPo battery systems (approximately 22.2V to 33.6V). Operating within this voltage range ensures optimal performance and prevents damage to the motor's windings and internal components.

Is this motor truly waterproof and suitable for agricultural use?

Yes, the Navigator MN501-S features an IP-rated waterproof and dustproof enclosure. This construction makes it highly resistant to moisture, chemical sprays, and dust, which is essential for reliable operation in agricultural spraying, crop-dusting, and other harsh outdoor environments.

What size propellers and mounting pattern does this motor use?

While the exact propeller size depends on your aircraft's design and desired thrust, this 300KV motor is typically paired with large-diameter (e.g., 18-24 inch) propellers for heavy-lift applications. It features a standard bolt pattern for heavy-lift motor mounts, and the shaft has a 6mm inner diameter with a 4mm outer diameter for secure propeller attachment.

What is the maximum continuous current and power this motor can handle?

The motor has a maximum power rating of 916 watts. With a working current range up to 37A, it is capable of sustaining high-thrust outputs. It is crucial to pair it with appropriately rated ESCs (e.g., 40A-60A) and ensure adequate cooling to utilize this performance safely.
