capable of 60-80 Amps
Operation:
1. Himax Brushless motors require brushless sensorless
speed controls. Failure to use a brushless sensorless
electronic speed control (ESC) can result in damage
to the motor and/or ESC. A Castle Creations Phoenix
series ESC is recommended for best performance.
The standard setting for timing advance is
recommended for best operation.
2. The three motor wires can be connected to the three
output leads of the ESC in any order. Check the
direction of rotation of the motor. If the motor spins in
the wrong direction switching any two of the motor
wires will reverse rotation. Be sure to insulate the
wires to prevent shorting which may damage the
ESC.
3. Do not shorten the motor wires. Shortening or
cutting the motor wires voids the warranty and may
cause motor failure. If the supplied connectors are not
to be used, remove them by desoldering.
DO NOT CUT THE CONNECTORS OFF!
4. Allow for proper cooling of the motor during operation.
With extremely high capacity batteries, care must be
taken to prevent excessive motor temperature.
Overheating of the motor is not covered under
warranty. Insufficient cooling can result in overheated
motors, even when operated at moderate power
levels.
5. Do not disassemble the motor. Disassembling the
motor voids the warranty. If service is required please
return the unit to Maxx Products for service.
6. Install the propeller after proper rotation has been
determined. Consult the ESC operation manual for
proper arming and use procedures. Be sure the prop
is clear before starting the motor. Once the battery is
plugged in stay clear of the prop, electric motors are
capable of extremely high torque and can be very
dangerous.
7. Verify the current draw. Excessive current draw will
overheat and damage the motor. Overheating is not
covered under warranty. The current must be within
limits at full throttle. Verify the power consumption.
Certain setups will run into the power limit before the
current limit. Observe the current and power limits,
which ever comes first. The 15-second max current
rating is for 3D or limited motor run applications.
Excessive use at high throttle settings when set up for
the 15 second rating will overheat the motor. Allow for
adequate cooling between bursts.
