Frequently Asked Questions

What is the maximum recommended battery configuration for the Rocket 4585 1580KV motor?

The motor is rated for a maximum voltage of less than 28V, which corresponds to a 7S LiPo battery (nominal 25.9V) or a fully charged 6S pack (25.2V). For optimal performance and safety, it is best suited for 6S to 8S LiPo systems, ensuring you stay within the specified voltage limit under load.

Is this motor compatible with standard 30.5x30.5mm or 25.5x25.5mm mounting patterns?

The provided specifications do not list the bolt hole mounting pattern. The 4585 size designation typically indicates a large-diameter motor (45mm stator, 85mm length) used for heavy-lift applications. You must verify the specific bolt circle diameter (BCD) and hole spacing from the manufacturer or product images before purchasing for your frame.

Can I use this sensorless motor with any standard BLHeli_S or BLHeli_32 ESC?

Yes, this is a standard sensorless brushless motor and is fully compatible with modern ESCs running BLHeli_S or BLHeli_32 firmware. Ensure your ESC is rated for the motor's high current draw (up to 78A) and the high voltage of your chosen battery system (6S-8S).
