01 Warnings

• Chip built in the motor,when matched with Hobbywing EZRUN MAX10 G2 esc, it not only has perfect compatibility, the ESC can automatically identify

the motor and build a pure/full sensor mode power system, providing better manipulating performance and more delicate manipulating feel.

• Compar

ed with the previous generation motor, the output power and efficiency are increased by mor

e than 3%. Under the same load, the motor

temperatur

e is effectively reduced.

• The independent high-pr

ecision encoder always outputs pure rotor position signal, which effectively avoids the interfer

ence of sensor signal and makes

the motor work stably in sensor state.

• CNC machined aluminum housing, high purity copper windings, advanced r

otor structur

e, 0.2mm silicon steel laminations, high-quality stainless steel

output shaft, high-pr

ecision bearing for high durability and smoothness.

• The innovative new sensor interface and rubber cover bearing have better waterpr

oof and dustproof effect than the traditional sensor motor.

• Please car

efully check power devices and manual of car frame to ensure the power pairing is reasonable. Avoid wr

ong pairing to overload and damage

the motor

• Always wir

e up all the parts of the equipment carefully. If any of the connections come loose as a result of vibration, your model RC may lose control.

• Never apply full thr

ottle if the pinion is not installed. Due to the extremely high RPMs without load, the motor may get damaged.

• Never allow the motor case to get 100 degr

ees Celsius (212 degrees Fahrenheit) because the magnets maybe demagnetized by high temperature.

In order to make the motor have longer service life and higher efficiency, we suggest to regularly check the bearing and clean the dirt in the motor. The

specific time depends on the frequency of using the motor and the site conditions. When installing, please follow the steps in the following assembly

drawing; when disassembling, follow the reverse steps.

Reasonable selection of gear ratio is very important. Improper gear ratio may bring you great loss. You can select the gear ratio according to the following points!

1. The running temperature of the motor

The motor temperature should be lower than 100 degrees Celsius (212 degrees Fahrenheit) in operation. Because high temperature may cause the magnets to get

demagnetized, the coil to get melt and short circuited, and the ESC to get damaged. A suitable gearing ratio can effectively prevent the motor from overheating.

2. The principle of selecting gear ratio

o avoid the possible damage to ESC and motor caused by the overheat, please start with a small pinion/a big FDR and check the motor temperature regularly.

If the motor and ESC temperature always stay at a low level during the running, you can change a big pinion/a low FDR and also check the motor temperature

egularly to ensure that the new FDR is suitable for your vehicle, local weather and track condition. (Note: For the safety of electric devices, please check the

ESC and motor temperatur

e regularly.)

1. Install the motor

There are 6 motor mounting holes in M3 specification, and the mounting holes are 5mm in depth,

befor

e installing the motor on the vehicle, please carefully confirm whether the specification of

the scr

ews is appropriate according to the thickness of the motor mounting plate to avoid

damage to the motor due to too long scr

ews.

2. How to Connect the Motor to an ESC

•

When connecting the motor and esc, please pay attention to the marked three-phase position

of A, B and C to ensur

e that the three wires of the motor and esc are connected correspond

ingly. Otherwise, it cannot run normally and even damage the esc and motor.

That is: Wire A of the esc matches wire A of the motor, wire B of the esc matches wire B of

the motor

, wire C of the esc matches wire C of the motor.

•

When the sensor wire of the motor is connected with the sensor wire of the esc, it shall be

connected corr

espondingly according to the arrow mark on the sensor interface.

3. Inspection

Before power on the esc, please check the reliability of the motor installation and the correctness

of all connections.
