DRONE MOTORS & PROPULSION SYSTEMS
From Micro to Heavy-Lift
FORKLS designs and manufactures BLDC motors, ESCs and propeller systems for every class of unmanned aircraft — engineered and built in Alberta, Canada.

THE MOTOR RANGE
From high-RPM agile outrunners to continuous-duty heavy-payload agricultural drives, engineered and manufactured in Edmonton, Alberta.
Micro & Compact Motors
Small-diameter outrunners for FPV, inspection, indoor, and light survey platforms. Built for fast throttle response and high power density, with balanced rotors and quality bearings that hold up to real flight hours instead of bench demos.
Mid-Size Motors
Motors for survey, mapping, delivery, security and industrial multirotor platforms in the mid-payload range. Optimized for efficiency and endurance — the flight-time band where propulsion losses decide whether a mission fits in one battery.
Heavy-Lift Motors
Large-diameter 36-pole outrunners in the 155–167 mm class, built for continuous high-torque duty on agricultural and heavy-lift platforms. NdFeB rotor magnets are selected for thermal margin, not just peak flux. Low-loss silicon steel stator laminations are paired with tight 0.75 mm radial air-gap control maintained through precision CNC machining of rotor bells, hubs, shafts, and crowns.
Fixed-Wing & VTOL Propulsion
Pusher, tractor and lift-motor configurations for fixed-wing and hybrid VTOL aircraft, including transition-optimized lift/cruise sets where hover motors and cruise propulsion are engineered and specified as a single, harmonious system.
ENGINEERING & MANUFACTURING
Every motor program is backed by instrumented thrust-stand testing, certified material verification, and precision CNC fabrication engineered to scale from prototype to volume production.
Designed & Tested In-House
Every motor program is backed by thrust-stand testing with instrumented, calibrated load cells. Operating parameters — Thrust, Current, RPM, and Temperature — are captured across the full flight envelope rather than single isolated peak points.
Materials Verified, Not Assumed
Magnet batches are audited against certification data, ensuring intrinsic coercivity margins at elevated operating temperatures. Silicon steel grades and heat treatment are verified with metallurgical suppliers before production.
Precision Machining
Multi-axis CNC turning and mill-turn operations on rotor bells, stator hubs, shafts, and crowns. The machining strategy scales smoothly from initial prototyping to near-net-shape volume manufacturing without redesigning the component.
Finishing Built for the Field
Rotor and housing surface finishes are selected specifically for environmental durability: resisting aggressive agricultural chemical exposure, thermal shock, and corrosive humidity over thousands of operating hours.
WHO WE BUILD FOR
Purpose-engineered propulsion solutions matched to operational profiles, duty cycles, and airframe demands.
Drone OEMs & Integrators
Propulsion units matched directly to your airframe dynamics, delivered with verified thrust, current, and thermal envelope data your engineering team can actually design against.
- Direct CAD integration files (.STEP)
- Matched motor, ESC, and prop curves
- Predictable lead times & scalable production
Agricultural Operators
Motors engineered specifically for the brutal duty cycle agricultural spraying and spreading actually imposes:
- Heavy Payload: Sustained peak torque under max fluid weight
- Repeated Cycles: Rapid battery swaps without thermal burnout
- Chemical Exposure: Sealed bearing cavities and treated windings
- Long Operating Days: Reliable uptime across critical spray windows
Industrial & Commercial Fleets
Inspection, survey, delivery, and security platforms where repeatable flight endurance, interchangeable spares, and zero downtime matter far more than headline bench claims.
- High MTBF (Mean Time Between Failures)
- Batch-to-batch consistent electrical parameters
- Comprehensive maintenance & spare component availability
R&D
Custom BLDC motor, ESC, and propeller design and rapid manufacturing. Tailored stator winding topologies, custom KV configurations, and hybrid VTOL lift/cruise optimization.
- Rapid prototyping in Edmonton facility
- Custom thermal & aerodynamic simulation

WHY FORKLS
Five principles that set our Canadian propulsion systems apart from commercial catalog resellers.
One Supplier, Every Class
From micro UAVs to heavy-lift agricultural drones from a single engineering team — maintaining consistent quality, testing standards, and parts control across a mixed fleet.
Systems, Not Components
Motor, ESC, and propeller are engineered and validated together on calibrated thrust stands to eliminate resonance, optimize switching frequency, and maximize total system efficiency.
Canadian Manufacturing
Engineering and production based in Edmonton, Alberta. Direct, unmediated access to the propulsion engineers who actually designed and machined your motor.
Real Test Data
Full-envelope thrust, current, RPM, and thermal curves captured from calibrated load cells on our Edmonton test stands, delivered alongside every product specification sheet.
Built to Be Built Again
Designed with manufacturing tolerances and repeatable volume production in mind from the first CAD sketch, ensuring prototype performance matches full-scale production batches.
FORKLS IN THE FIELD
Agricultural field validation, flight endurance trials, and test stand validation in Canadian operating conditions.
