In an effort to answer a number of questions relating to motor timing we have compiled some information to help you better understand static motor timing and its effects with our Ballistic Series of motors.
“How many Degrees of Timing does my Ballistic Motor have?”
Our Ballistic motors come with their timing calibrated and set from the factory. Using custom built and calibrated electronic equipment we set each and every motor to 30 degrees of timing. After Calibration the timing label is added and this set timing corresponds to the “N” on the timing label on the side
Each line on the label denotes a 5 degree change, so the timing available on the motor the label corresponds as follows:
-3 -2 -1 N +1 +2 +3
15 20 25 30 35 40 45
N = 30 (rows do not line up correctly)
SPECIAL NOTE: The timing we are describing is the ACTUAL ELECTRICAL TIMING in the motor, not just some arbitrarily reference made from a point on the outside of the motor like many of our competitors' motors. This makes comparing timing settings between different brands of motors difficult without the proper equipment.
“What Does Timing Adjustment do?”
We set our timing at an optimized point for most general applications. Adjusting the timing should only be done in small increments and with great care to observe the changes in system performance and temperatures.
WE RECOMMEND THAT YOUR SYSTEM’S TEMPERATURE NEVER EXCEED 160 DEGREES FARENHEIGHT.
When adjusting the timing, we recommend adjusting the timing, at most, 1 notch, or 5 degrees at a time.
When you turn the timing up to a more positive number (from N to +1) your motor will produce more no-load RPM and generally suffer a slight reduction in torque. To combat excessive heating brought about the loss of torque we recommend gearing down 1 tooth on the pinion for each notch (5 degree increment).
When turning the timing down, to a more negative number (from N to -1) your motor will produce less no-load RPM and generally experience an increase in torque. To combat a loss of top end speed brought about by the loss of RPM we recommend gearing up 1 tooth on the pinion for each notch (5 degree increment).
Ballistic Timing Questions, Part 2
“How do I set my Ballistic to zero degrees of timing?”
The factory timing for the Ballistic is 30 degrees of timing and corresponds to the N on the timing label on the back of the motor.
We do not recommend running zero degrees of timing for most applications and would recommend running at least 5 degrees of timing to ensure proper operation of the motor.
NOTE: When running your timing lower than the pre-set factory 30 degrees your reversing function of your Novak ESC may not work properly as it accounts for this 30 degrees of timing in its commutation sequence.
To adjust the motor to this lower 5 degree timing setting:
1. Loosen the three 1.5 mm hex head screws on the back timing cap of the motor
2. Turn the end-cap clockwise until the stationary notch on the endbell lines up with the edge of the label as demonstrated in the picture below:

3. Re-tighten the three 1.5 mm hex head screws in a circular pattern to ensure that they are all tightened evenly.
