SkyRC ARES PRO V4 540 Sensor Brushless Motor SPEC 21.5T

Features

• Designed for Spec Classes: Precisely wound 21.5T motor, optimized for maximum efficiency and sharp torque delivery under regulated Stock and Spec racing rules.
• Advanced Sensor Precision: Uses a dedicated internal Hall sensor to eliminate cogging or jerking at low RPM, ensuring a direct and predictable power response across the entire throttle range.
• Redundant Dual Sensor Ports: Equipped with two multidirectional sensor connectors that streamline wiring in tight chassis layouts and provide a reliable, built-in communication backup.
• Infinitely Adjustable Mechanical Timing: Features an adjustable aluminum end cap with visible index marks (0° to 60°) for quickly tuning torque delivery to track conditions and grip.
• High-Quality Copper Windings: Wound with high-grade copper wire that withstands temperatures up to 220°C to drastically reduce resistance, optimize power conversion, and minimize heat buildup.
• Balanced Iron-Core Rotor: Features a precisely balanced internal rotor (Phi12.5 × Phi7.15 × 25.2 mm), protected by an explosion-proof, heat-resistant 200°C construction for smooth rotation and durability.
• 200°C Neodymium Magnets: High-quality, heat-resistant neodymium magnets deliver robust torque profiles and prevent magnetic degradation during long, demanding races.
• Vented CNC Aluminum Housing: The precision-machined aluminum housing features enlarged vents at the rear to maximize direct airflow over the sensor circuit boards and internal core.
• Low-Resistance Solder Tabs: Heavy-duty, high-current solder tabs minimize ESC power loss and ensure maximum current delivery to the stator windings.
• Fully Rebuildable Architecture: The fully modular configuration makes it easy to disassemble the world-class housing, stator, rotor, and bearings using standard RC tools for routine maintenance.
