Operation:
1. Himax Brushless motors require brushless sensorless speed controls.
Failure to use a brushless sensorless elec-
tronic 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 wires of the motor 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.
