EP Brushless Motor 2203-1700 – Lightweight, Powerful RC Drive with 3mm Shaft
The EP Brushless Motor 2203-1700 is a compact, sensorless brushless DC motor specifically designed for RC aircraft and other modeling applications. With a no-load speed of 1700 kV per volt and an outer diameter of 27.5 mm, it offers an efficient combination of power and low weight.
Brushless technology for high efficiency and long life – no brush wear
Sensorless control reduces complexity and weight, ideal for lightweight flying models
Compact design: only 27.5 mm outer diameter and 21 mm length at just 30 g – perfect for narrow fuselages
1700 kV no-load speed enables high RPM for fast propellers or impellers
3 mm motor shaft diameter compatible with many standard propeller adapters and impellers
What sets the EP Brushless Motor 2203-1700 apart
The motor impresses with its excellent power-to-weight ratio. With just 30 grams of its own weight, it delivers enough thrust for park flyers, small gliders, and light multirotors. The sensorless control makes it particularly easy to operate with standard ESCs using BLHeli or SimonK firmware. The precision-machined 3 mm shaft runs smoothly and with low wear on integrated ball bearings.
Ideal for...
This motor is aimed at RC modelers looking for lightweight, efficient drives for aircraft, gliders, or small helicopters. Thanks to its compact dimensions, it is also suitable for custom builds with tight space constraints such as delta wings or flying wings.
How to use the EP Brushless Motor 2203-1700
The motor is connected to a suitable sensorless brushless ESC that generates the three-phase current for the motor's three phases. Pay attention to the correct speed selection – for a 1700 kV motor, small-pitch propellers (e.g., 7x3 or 8x4) are recommended for an efficient combination. Mounting is done via the side holes; the 30 g weight can be offset by battery placement.
