CO2 Impact
By purchasing this pre-owned gearmotor, you are contributing to a circular economy and avoiding the CO2 emissions of new production. This 36.0 kg unit represents an estimated CO2 saving of 360 kg, which is comparable to the emissions from driving a standard car for over 1800 kilometers.
Availability
This item is a used unit in good cosmetic condition, with the specific exception of a damaged rear connector. It is sold as-is. Functionality of the feedback system cannot be guaranteed due to the damage. Order now from PLC2Day for expert support and fast delivery.
FAQ
Question? What type of controller is required for this DY90S permanent magnet motor?
Answer
This is a synchronous servomotor and requires a suitable servo drive or frequency inverter with synchronous motor control capability, such as the SEW-EURODRIVE MOVITRAC or MOVIDRIVE series. It cannot be run directly from the mains supply like a standard asynchronous motor.
Question? The description mentions a damaged rear connector. What is this connector for and can the motor still be used?
Answer
The connector on the rear of a servomotor is typically for a feedback device like an encoder or resolver. Depending on the application's control mode (e.g., sensorless vector control vs. closed-loop positioning), the motor might be usable for simpler tasks. However, for precise positioning, the feedback system would need to be repaired or replaced. The functionality is not guaranteed.
Question? What does the /B/TH suffix in the type number R47 DY90S/B/TH signify?
Answer
The /B indicates the presence of an integrated mechanical brake, which is confirmed on the nameplate as a 230V AC brake with 40 Nm torque. The /TH typically signifies a thermal protection sensor (thermistor or thermostat) embedded in the motor windings to monitor for overheating.PLC2DAY is not an authorized distributor, reseller or representative of the products featured on this website.
