Learn how Vertiq’s motor and ESC modules affect thrust data, including insights into throttle modes, data presentation, and why realistic performance limits are emphasized. This article helps clarify key factors for safe, reliable aircraft operation.
Many users unfamiliar with Vertiq motors and ESC modules often have questions about our thrust data, which is presented differently from other manufacturers. The unique configurability and controllability of our modules are key to understanding this difference.
Why is there no throttle column? Vertiq modules support three throttle modes: PWM Mode, Voltage Mode, and Velocity Mode, all of which are customizable via our IQ Control Center. Each mode interprets throttle commands differently:
- PWM Mode: Throttle maps to a percentage of supplied voltage but can vary with battery levels, leading to inconsistencies.
- Voltage Mode: Throttle is mapped to a specific voltage, ensuring consistent performance even as battery levels fluctuate.
- Velocity Mode: Throttle is mapped to a specific velocity, optimizing performance and response time.
This unique configurability means that throttle percentages don’t have a fixed meaning, which is why we present data in increments of 1V or 2V, making it more consistent than industry standards. Unlike other manufacturers who often use a fixed PWM throttle and display data in 10% increments, Vertiq’s data reflects a more precise and dependable measure of module performance.
Why does the test data suddenly stop? We only publish data up to the continuous torque limit of each module to ensure realistic expectations. While our modules can exceed these limits briefly, prolonged operation beyond them can lead to overheating. We do not publish data above this threshold to avoid misleading users about potential thrust and torque capabilities under real-world conditions.
Understanding how our modules operate within safe limits is essential for achieving long-term reliability and performance. Most other manufacturers publish full test data, which may show performance that could lead to overheating or derating under actual operating conditions. Vertiq’s approach prioritizes safe, continuous performance, encouraging users to select motor-ESC-propeller combinations that can consistently meet their maximum thrust requirements.
