- Motor Mounting: Motors just like the 0802 and 1103 are sometimes mounted utilizing a 6.5mm x 6.5mm gap sample.
- Weight: These motors are very light-weight, usually round 2g to 3g.
- Pole Rely: Generally, Whoop motors have a 12-pole design (6 pairs of poles).
- Motor Windings: Brushless motors for Whoop frames should not labeled as clockwise (CW) or counterclockwise (CCW) since their rotation route might be modified within the flight controller settings.
Micro Frames (4 to 7 inches)
Micro frames strike a stability between agility and energy, making them versatile for each indoor and out of doors flight. Right here’s what to think about:
- KV Vary: Motors with KV scores starting from 4000 to 6500 are appropriate for micro frames.
- Motor Measurement: Select motors sized between 1404 to 1606 to fulfill the calls for of micro-sized drones.
- Stator Measurement: A typical stator dimension for micro motors could possibly be 14mm in diameter and 4mm in peak (e.g., 1404).
- Torque: Micro motors provide extra torque in comparison with Whoop motors, resembling 0.05 Nm for a 1404 motor.
- Motor Mounting: Motors like 1404 and 1606 usually use a 9mm x 9mm mounting sample.
- Weight: These motors usually weigh between 8g to 15g.
- Pole Rely: Micro motors usually function 14-pole designs (7 pairs of poles).
- Motor Windings: Micro motors comply with the identical CW and CCW labeling conference for constant propeller tightening.
Mini Frames (7 to 10 inches)
Mini frames are standard in FPV racing and require motors that ship each pace and torque for optimum efficiency. Take into account the next:
- KV Vary: Go for motors with KV scores from 2400 to 2750 for mini frames.
- Motor Measurement: Motors sized between 2205 to 2306 are perfect for FPV racing drones.
- Stator Measurement: Widespread stator sizes embrace 22mm in diameter and 5mm to 6mm in peak (e.g., 2205 or 2306).
- Torque: These motors present substantial torque, resembling 0.15 Nm for a 2205 motor.
- Motor Mounting: Mini motors usually use a 16mm x 19mm mounting sample.
- Weight: These motors usually weigh between 25g to 35g.
- Pole Rely: A typical pole rely for mini motors is 14-pole (7 pairs of poles).
- Motor Windings: These motors are labeled CW and CCW to make sure correct propeller tightening, essential for racing drones the place propeller loss may end up in race-ending crashes.
Commonplace Frames (10 to 18 inches)
Commonplace frames are designed for leisure and cinematic flying, requiring motors able to dealing with heavier payloads with stability and effectivity. Right here’s what you want:
- KV Vary: Motors with decrease KV scores between 800 to 1600 are appropriate for traditional frames.
- Motor Measurement: Go for bigger motors starting from 2806 to 3210 to help the burden of heavier payloads.
- Stator Measurement: Stator sizes for these motors could be round 28mm in diameter and 6mm to 10mm in peak (e.g., 2806 or 3210).
- Torque: Commonplace motors provide much more torque, for instance, 0.5 Nm for a 2806 motor.
- Motor Mounting: These motors use a 19mm x 19mm mounting sample.
- Weight: These motors usually weigh between 50g to 80g.
- Pole Rely: Usually, these motors have a 14-pole design.
- Motor Windings: Comply with the CW and CCW labeling for consistency in propeller tightening, vital for sustaining stability with heavier payloads.
Giant Frames (over 18 inches)
Giant frames are reserved for skilled cinematography or industrial purposes, requiring motors that may present substantial raise with most effectivity and stability. Listed here are the specifics:
- KV Vary: Motors with very low KV scores beneath 800 are appropriate for big frames.
- Motor Measurement: Take into account motor sizes like 4210 or bigger to help the burden of heavy payloads.
- Stator Measurement: Giant motors could have stators like 42mm in diameter and 10mm or extra in peak (e.g., 4210).
- Torque: These motors present important torque, resembling 2 Nm for a 4210 motor.
- Motor Mounting: Giant motors are mounted with heavy-duty screws and usually use a 30mm x 30mm mounting sample.
- Weight: These motors usually weigh over 150g.
- Pole Rely: Larger pole counts, resembling 24-pole designs (12 pairs of poles), are widespread for smoother efficiency.
- Motor Windings: These additionally comply with the CW and CCW labeling conference, making certain correct propeller tightening for prolonged flight durations.
