Product Description:
The SS451-1021 synchronous motor, which is part of Danaher's dependable Slo-Syn series, is designed to offer precise and accurate speed control, especially for modern industrial applications. This gadget operates on standard 240 VAC single phase power supply eliminating the need of custom power solutions, making the drive easier to install in existing industrial setups. With its 72 RPM (60 Hz or 50 Hz, respectively) speed rating, the module is ideal for machine users who are worried about repetitive operations in automated environments since it can move smoothly and at low speeds with no vibration.
The commonly used industrial mounts of the SS451-1021 type are built with a NEMA Size 34> frame, which eliminates the need for extra adapters. It has a strong minimum torque of <<450 oz-in to ensure that it can support high loads without slipping. Whether configured with leaded connections or a terminal box, this innovative device supports flexible installation layouts. The use of an external phase-shifting capacitor network ensures proper phase alignment, resulting in stable torque and smooth, efficient operation even under rated loads.
This Slo-Syn model offers several performance-focused features, including fast startup—reaching full synchronous speed within 5–25 ms, therefore, enhancing timing accuracy in high-throughput environments. An optional DC holding torque system can lock the rotor when power is off and hence preventing load drift. For even more torque, optional gearboxes are supported to further improve durability under peak conditions. The lightweight 4.45 kg design of SS451-1021 also makes it easy to handle, reducing strain on support structures and simplifying maintenance or replacement.
Frequently Asked Questions about SS451-1021:
Q: Can this SS451-1021 device handle sudden power loss?
A: SS451-1021’s optional DC holding torque enhancement locks the rotor when AC is removed. It prevents load drift during brief outages.
Q: How does the NEMA 34 frame benefit this module's installation?
A: The NEMA Size 34 frame matches standard industrial mounts and further avoids custom brackets and speed up assembly.
Q: What motor's efficiency can I expect under load?
A: The model SS451-1021 is engineered for efficient performance at rated load. It can reduce energy consumption and lower operating costs.
Q: What mounting options exist for SS451-1021?
