Product Description:
This AC servo synchronous motor SS242LEG4 is produced by a global leading manufacturer Danaher. Named under the top-rated Slo-Syn Synchronous Motors, this model is a reliable option for industry owners owing to its smooth synchronous motion and precision. Providing a speed of 72 RPM at 60 Hz and 60 RPM at 50 Hz, the device can easily work with local and international power systems on a standard voltage of 240 VAC. With these characteristics, it ends up achieving consistency in speed while minimizing vibration.
The compact 2.72 inch frame and quick leaded plug configuration is designed for easy wiring and razing of the recorder is ideal for industrial maintenance. This commercial module from Danaher employs a 4:1 gearbox that multiplies output torque and reduces output speed, making it ideal for high load applications. Extended rear shaft allows encoders or couplings to be added giving the users more flexibility in specialized setups. It is built to endure harsh environments and operates between –40 °F and 140 °F and stores at 266 °F or higher safely. And, its IP42 rated enclosure absorbs dust and filters out brief and light moisture, thus extending its life considerably.
This SS242LEG4 motor delivers a minimum running torque of approximately 240 oz-in to guarantee consistent performance even during heavy startup loads. It can stall indefinitely without overheating which is essential for holding positions in jam-prone systems without risking damage. With rapid acceleration to full synchronous speed in just 5–25 ms, the unit improves process timing in high-cycle applications. Its ability to withstand 5–95% non-condensing humidity and altitudes up to 30,000 ft makes it a durable and versatile solution across a wide range of modern industrial applications.
Frequently Asked Questions about SS242LEG4:
Q: How does SS242LEG4 perform under high humidity?
A: It tolerates 5–95% non‑condensing humidity which prevents moisture-related failures and maintains insulation integrity to avoid short circuits.
Q: Can SS242LEG4 operate at high elevations?
A: The drive runs up to 30 000 ft (9 100 m) altitude which supports mountain-top installations. It prevents performance loss due to reduced air density.
Q: What mounting options exist for SS242LEG4 motor?
A: You use the 2.72 in frame size for compact mounts or add the extended rear shaft for auxiliary couplings. Further, you can secure it with standard NEMA 34 brackets.
Q: How reliable is SS242LEG4’s startup under load?
A: SS242LEG4 delivers 240 oz‑in minimum running torque which prevents stalls at startup and secures heavy loads without slipping.
Q: What wiring configurations suit Danaher’s SS242LEG4 drive?
A: The drive is available with leaded plug or terminal box connections. You choose the layout that matches your control cabinet design.
