Alpha ESC with telemetry output

Alpha ESC

About

The page is about the T-Motor Alpha 60A LV 500Hz 4~6S ESC but apart from the type specifications can be referred to for all the Alpha ESC types.

Well, please add more information if you come across some interesting facts...

One of the facts is that the code is not in the master branch of Paparazzi yet, code is tested and still debugged as of 20180605. More robust error handling needs to be added and more in the fikled testing is the consensus.

Manufacturer hype

T-motor's ESC based on FOV (Sine Wave) with intelligent algorithm to satisfy the requirements of professional applications for efficient, accurate and stable motor control. Alpha series ESC's are more efficient compared to traditional ESC's using square wave driving and in combination with U series motor can achieve long flight times. Alpha Esc's features multiple protection system and its intelligent design enables to timely detect & adjust parameters such as low voltage, over current, throttle loss signal, motor lock and short circuit etc. thus prolonging the lifespan. Nano coating technology is adopted using IP55 Ingres Protection, making this ESC Anti corrosion, dust resistance and waterproof, thus allowing safe operation in any type of environments.

Alpha series ESC's are revolutionary esc based on (FOV) using Sine wave algorithm to satisfy the requirements of professional applicaitons for efficient, accurate and steady motor control. Lightweight compared to other esc's of same size using Ultra lite shell makes cooling efficient and contributes to lower temperature by 10%. Active braking functions allows recycle of energy allowing to recharge the battery when slowing down and increasing flight times.

  • Power cable: 14AWG, 175mm (Silicone wire Red/Black)
  • Signal cable: PVC flat cable with JP 3P male connector

FOC

FOC: abbreviation of "field-oriented control" . The principle of FOC is to control motor output via the adjustment of current flow and angle, the features of which can be used to control motor magnetic field a. torque Current and voltage output of 3 phases is presented by vectors in mathematical model, that is why FOC is also known as "vector control" . An revolutionary ESC based on FOV (Sine wave) with intelligent algorithm to satisfy the requirements of professional applications for efficientaccurate and steady motor control.

High Efficiency ALPHA ESCs are more efficient compared with traditional BLDG ESCs (square wave driving). Combo use with T-MOTOR U-series motors long flight time can be easily achieved.

Motor Lock-up Protection

Strict Protection Nano coating technology is adopted In ALPHA ESC PCB A. I P55 grade keep water and dust away Protect ESC from the damage of liquid corrosion for safe operation.

Efficient Cooling FOC driving without hybrid current reduces ESC temperature. Novel cooling design contributes to temperature drop by 1 0%+ ESC runs at ease at hot environment

Active Braking

With active braking function motor recycles energy when slowing down. With recycled energy motor charges the battery reversely for flight time extension.

Telemetry

A module surprisingly called "Alpha ESC" is available to read the data. Read the documentation via Doxygen or a bit, maybe outdated information here on this page...

  • The Black and White cable is regular servo connector with PWM to control ESC speed output
  • Yellow cable give pulses for fast RPM measurment
  • The black, Red and White cable sends a serial data stream. Connect Black to GND and White cable must be connected to a serial RX port on the autopilot. Disconnect the red wire

Messages

To get this there is no universal ESC messageclass (Yet) in use for this. Would be nice if someone would alter and add this...(AKA open source)

Add this to your custom messages XML for the time being
