ESCs - The 20A Vortex 250 ESC
Overview
The ESCs used in the Vortex are a full-custom design, which uses a potent 32-bit ARM
processor.
Their diminutive 9.4mm width allows them to be inserted into the carbon fiber arms of the
Vortex 285, or into the plastic ESC covers of the 250, where they are well protected against
the elements, and from physical damage from passing tree-branches.
The ESCs come pre-configured for all motors supported by the Vortex, and they have also
been used successfully with various aftermarket motors used by our test team.
NOTE: The first generation of EzESCs cannot have their firmware upgraded by end-users.
Upgrading them requires special equipment, used in the factory, and at ImmersionRC
repair centers.
RotorSENSE
A unique feature of the ESCs used in the Vortex is RotorSense.
This feature puts an end to the decade-old ‘wire-swapping’ technique used to get brushless
motors to spin in the correct direction.
Once props are installed, at power-up before arming the flight controller, a simple spin of a
prop will program the rotation sense.
NOTE: This procedure may be performed with props in place, or props removed. For
safety’s sake it is recommended that props are removed.
If they are left installed, it is recommended to use a stick, or other object instead of a
finger to flick the prop.
The full procedure is as follows:
1) Cycle power to the quad to ensure that the flight controller is not armed.
2) Spin the motor in the desired direction. If the ESC recognizes the spin, two short beeps
will be generated.
3) Spin the motor again in the desired direction. If the ESC recognises the spin, 5 longer
beeps will be generated and the ESC has learned the direction.
IMPORTANT: ImmersionRC ESCs
DO NOT REQUIRE CALIBRATION
. The calibration
process required by most ‘budget’ ESCs is required since a precise quartz oscillator is not
used in the ESC. The ImmersionRC ESCs all include this critical component, and therefore
never need calibration.
