Overview
The MAD AM40 34KV 52x22 Power System Kit is a heavy-lift power system kit combining an AM40 motor, AMPX FOC ESC, and compatible carbon-fiber propeller options for high-thrust multirotor platforms. The AeroMax 40 KIT 34KV set is specified for up to 24S (LiPo) operation and provides published thrust, efficiency, and dimensional data for integration.
Key Features
- Two kit options:
- Kit A: without lock propeller function; includes 1x ESC (standard firmware) and 1x CW or CCW propeller.
- Kit B: motor features a magnetic encoder to detect and lock the propeller at a specified stop position (requires compatible ESC firmware); includes 1x ESC (with required firmware) and 1x CW or CCW propeller.
- ESC supports Dual CAN/PWM throttle (communication interface: CAN; PWM input pulse width 1100-1900us).
- FOC ESC system with DSP chip and stated dynamic response of 0.28 s.
- Propellers listed as high quality carbon fiber + resin (FLUXER PRO series).
- Vacuum-sealed coils and real-time temperature monitoring are described for the motor system.

Details
The AeroMax 40 KIT 34KV power system kit pairs a motor, propeller, and ESC for a clean, matched propulsion setup.
MAD AM40 power system kit highlights include 40 kg rated thrust, 86.5 kg peak thrust, and a 3.6 kg ultra-light motor weight design.
The MAD AM40 34KV power system kit pairs an AMPX FOC 250A 24S ESC with the AM40 motor and 52x22 prop options, with a motor operating curve chart and key parameters for setup planning.
Test data at 98V lists throttle, voltage, current, power, torque, RPM, thrust, and efficiency for the AeroMax 40 34KV setup with a Fluxer Pro 55x22 prop and AMPX FOC 250A 24S ESC.
AM40 motor and AMPX FOC 250A 24S ESC dimension details help plan mounting clearances and cable routing for the power system kit.
The kit includes an ESC line-sequence wiring reference and dimensioned Fluxer Pro prop layouts to help with setup and clearance checks.
The AMPX FOC ESC supports easy tuning and OTA updates, with dual CAN/PWM throttle support and SiC MOSFET hardware.
The kit’s carbon fiber propellers use a bio-inspired airfoil and 3D twist design for a stronger, steadier feel with reduced noise.
The MAD AM40 power system components are validated with 1,000-hour endurance testing, -40°C to 85°C thermal cycling, 48-hour salt-spray corrosion resistance, and IP45 waterproof testing.
