Description
Description
With a reinforced internal 8mm shaft diameter and larger bearings, the 4730EC Eclipse Series is designed to handle the immense torque of its 0.1mm EGODRIFT custom stator effortlessly.
The reduced eddy currents and cleaner commutation result in a near-instantaneous throttle response and yet improved efficiency and performance. Experience a new generation of power, torque, and control with the 47EC Eclipse Series.
Did you know?
The 540Kv version weighs only 554 grams, a mere 34 grams more than its 4530HT counterpart, despite its 2mm wider stator and increased shaft and bearings diameter. The 570Kv model rings in at only 559.5g.
Key Features:
- World’s first 0.1mm stator laminations for unmatched efficiency
- Robust 8mm internal shaft and larger bearings
- Superior torque and power with cooler running temperatures
- Ideal for high-demand flight conditions

Specifications
All the products in our store are manufactured by us with great care. You knew that, but we get why you clicked the tooltip - and thanks.
The stator size of our motors is indicated as a combined number, where the first two digits refer to the stator width, and the last two digits refer to the stator height.
So a 4730 stator size refers to a motor with a stator width of 47 mm, and a stator height of 30 mm.
On large industry models with a stator diameter in exess of 100 mm (like our Jetstream Heavy Duty Series, these numbers are seperated by a dash, like 100-30 or 150-50.
The motor configuration gives you information about the number of stator arms/slots (N) and magnetic poles (P). So a 12N10P denomination refers to a motor with 12 arms and 10 poles.
This information includes the number of mounting holes, their respective thread size, and the bolt circle on which the holes are placed — shown as the number in brackets.
Example 1: "4x M4(30)"
This means that the motor features four M4 mounting holes, placed on a 30 mm bolt circle.
For extended compatibility with a wide range of models, some of our motors feature a combination of different mounting hole sizes and/or bolt circles. In this case, the information is shown as follows:
Example 2: "2x M4(30) + 2x M3(25)"
This means that the motor features two M4 mounting holes placed on a 30 mm bolt circle, and two M3 mounting holes placed on a 25 mm bolt circle.
Don’t worry if only two of the mounting holes, opposite to each other, line up with your mounting bracket or motor plate. Using only two screws is perfectly fine — but as with any metal thread, always use threadlocker.
This number refers to the legth of the motor body excluding the shaft, so from the mounting plate to the top of the rotor.
This number refers to the width (maximum extension from side to side) of the motor.
When checking the clearance in your frame, this is the number to compare it against.
Shaft Compatibility
Shaft Compatibility
The standard 6x35mm shaft length option fits most modern 700 size helicopters such as:
- SAB (Goblin)
- Goosky
- OMPhobby
- SoXos
- XLPower
The longer 6x55mm shaft option is needed for:
- Mikado Logo
- Align
- Gaui
- Various scale mechanics
Additionally, there is a new 8x55m shaft option for all trainer & scale mechanics supporting (or requiring) an 8mm shaft diameter.

World's 1st 0.1 mm lamination motors by EGODRIFT
Once you go black you always go back 🖤 - unbelievable power delivery , smoothness and efficiency , you won’t regret it 🥶
I hesitated for a long time about whether the upgrade would be worth it, but after the very first flight, all my doubts vanished. This motor is a true masterpiece! I'm running it on a 700-size heli, and the torque is simply mind-blowing: even during (try) the hard 3D maneuvers and sudden load changes, it holds the RPM like it's locked on rails.
I bought the EGODRIFT 4730EC 570KV motor to combine it with a Hobbywing 260 V5
ESC and the stock pinion on my M7R.
I have always been a big fan of the black design, efficiency, power delivery, and thermal performance.
However, thanks to the 47EC series, my heli's now make the simulator look and feel slow.
The power delivery and response time have completely redefined my understanding of the word "instantly."
It truly feels like upgrading from a 30Hz monitor to a 500Hz monitor.
I’ve been using EGODRIFT motors since my first 4530HS 510kv, the reliability and customer care has been second to none.
The 4730EC 540kv continues this trend with more power, cooler running and great efficiency.
As usual it works flawlessly with my ESCs and I thoroughly recommend any of the EGODRIFT range to pilots of all skill levels.
It’s not just a motor - it’s an investment that allows reliable performance in a challenging hobby…
