Turnigy RotoMax 50cc Size Brushless Outrunner Motor

Turnigy RotoMax 50cc Size Brushless Outrunner Motor
Turnigy RotoMax 50cc Size Brushless Outrunner Motor

Upgrade your 50cc size gas engine model with the Turnigy RotoMax 50cc Brushless outrunner motor. This motor will provide clean and efficient power for your large scale aircraft without the mess and hassle of nitro fuel.

When combined with a 10s Lipoly battery, 24x12/26x12" Propeller and a 180Amp ESC the RotoMax motor will supply punchy, responsive power that only an electric setup can provide.

This motor is specifically suited for carbon fiber & wooden propellers and features an IC style 4 bolt hole design. The shaft has also been tapped to suit a 4mm bolt to make fitting a spinner of your choice easy.

Hello, can anyone tell me what the distance between on side and the other is to mount the bolts on? Thanks

Dear friends, the brushless motors are three-phase motors, the phases are switching / alternating so that at the same time the unit of time we are always only two at a time, then: phase 1 and phase 2 °* then Phase 2 and Phase 3 and finally phase 3 °* and 1 °* dinuovo phase and the cycle .of again as before All this is to use a square waveform (in effect given the reactive component, a trapezoidal wave) obtaining from 80 to 95% on the ratio Pin / Pout, and also avoid the conflict phase, (short circuit conflict, due to the harmonic content of a square wave) The frequency determines the RPM wave, while the PWM determines the current, then the Power.

Dear friends, the other important thing to choose is the current I Max? for Max Power eg for obtaining 5000 Watts is better to use 8 or 12 cells Lipo, 37 volts or 44 volts? - W = V / I and 5000 / 29.6 = 168 Amp and 5000/44 = 112 Amp, then we will have a parity of power lower current and a less chance of melting the winding, also we will have less distortion of the waveform of the PWM (iron saturation). For the same period of duration of a flight we could use batteries from 3800 ... 4000 mAmp decreasing the weight, or increase the flight time with a current minor -5 x 29.6 V = 148 kW and 5 x 44 V = 220 Kw Also available Mario Begni

I got impatient so retro fitted the rotomax into my Hanger 9 260 27pcnt, the whole conversion from DLE55 to rotomax took about 2hours and consists of 2 x 6s 5000mah turnigy Lipos, 160HV speedy and the prop off the DLE which is a 23x8 carbon Mej. Results on Eflite watt meter 4580watts @ 103 amps after 20sec

Measured Data: Kv= 190; Ri=16mOhm; Io=2.3A@8V; Weight 1070gr. Motor has 28poles and 24 tooths. Mechanical precision very good. Winding could be better to come down with Ri to Hacker Q80-8M but at this price an excellent motor.

Tried it some minutes ago with 21x10 woodprop. Batteries: 2x Rhino 6s1p 4900mAh 25C with more than 100 cycles. Current: max. 120A Voltage: 43V at full throttle Power: 5160 Watt Because the power will be even more with new batteries (with higher C-rate (>30C)) I will mount a Will try it again with new batteries and a 20x10 prop.
