26 • VELINEON POWER SYSTEM
The VXL-3s electronic speed control is capable of controlling brushed,
brushless, and sensored brushless motors. The VXL-3s auto-detects the
motor type and has numerous built-in safeguards to prevent damage
from miswiring or damaged wiring.
Sensored brushless motors
The VXL-3s is fully compatible with sensored brushless motors. Sensor
motors use an additional sensor installed in the motor to communicate
rotor position to the speed control. The VXL-3s features a covered
auxiliary port that accepts aftermarket motor sensors on the front face
of the unit. The VXL-3s has built-in Sensor Motor Backup Protection
to prevent damage if the sensor leads or phase leads become
disconnected. If a sensor lead becomes damaged or is disconnected,
the VXL-3s automatically switches to sensorless brushless operation.
The VXL-3s also features Sensor Phase
Detection. When a sensored brushless motor
is connected, the VXL-3s will check for proper
wiring. If the motor phase wiring is incorrect,
the VXL-3s will not apply power to the motor
until it is wired correctly. Brushed motors
For the ultimate in versatility, the VXL-3s has no motor limit when
used with a brushed motor. This allows you to use any readily
available 540 or 550 size brushed motors in your VXL-3s equipped
vehicle. Always be sure to follow all break in and maintenance
instructions set forth by the motor manufacturer. The VXL-3s
automatically detects what kind of motor it is connected to so no
programming actions are required to use brushed motors. Simply
be sure to properly connect the motor to the speed control as shown.
• Motor positive (+) should be connected to phase A (blue).
• Phase B is not used.
• Motor negative (-) should be connected to phase C (white).
If the wiring is reversed, the motor will operate in reverse. If the
motor is wired incorrectly (using phases A+B or B+C), the VXL-3s will
send short pulses to the motor and turn off the LED indicating a fail
safe mode. It will not return to normal operation until wired properly.
Sensorless brushless motors
Sensorless motors are the easiest and most reliable brushless motor
type. The VXL-3s is optimized to deliver the smoothest possible
sensorless motor performance. The Velineon 3500 is a sensorless
brushless motor. The wiring (phase alignment) of the motor determines
its direction of rotation. Refer to the wiring diagram on page 15.
