Frequently Asked Questions
Common questions about the YC-90 90W / 120W
What is the maximum torque output at the highest gear ratio?+
At a gear ratio of 1:300, the maximum permissible output torque is 2.45 N·m. This represents the mechanical limit of the gearbox, regardless of motor output power. Please refer to the parameter table for the full ratio-torque map.
How does the 90W model differ from the 40W and 60W variants?+
The 90W model uses a larger copper winding to deliver higher continuous power output. The motor frame size (90mm) and shaft diameter (Φ14mm) are identical, but the 90W model is wound for higher sustained torque and speed at rated load.
Is this motor suitable for outdoor installation?+
The standard model is IP44 rated — protected against solid objects over 1mm and water splashing from any direction. For outdoor or wet environments, please contact us to discuss upgraded IP ratings.
Can I use this motor with a frequency inverter (VFD)?+
Our standard YC series motors are single-phase capacitor-run motors optimised for direct mains or ESC control. For VFD applications please contact us — we can advise on compatible configurations or alternative models.
How is the ESC speed controlled?+
The integrated ESC includes an adjustment knob for manual speed setting, and most models also accept an external 0–5V analog signal for automated speed control from a PLC or controller.
Does the ESC affect the motor's torque output?+
The ESC maintains consistent torque delivery across the speed range. At very low speeds (below 20% of rated), torque may reduce slightly — contact us if your application requires high torque at very low speeds.
