OTIS DAA20220DE Traction Motor

OTIS DAA20220DE, part of the NEOTEK 60 series, is a high-performance traction machine engineered to provide the core motive force for elevator systems in a wide range of buildings. This robust motor is designed for reliability and efficiency, making it a premier choice for mid to high-rise applications where consistent performance is critical. Its primary function is to drive the elevator hoist mechanism, ensuring the smooth, safe, and precise vertical transportation of people and goods.

Engineered for versatility, this traction machine supports a rated payload from 550kg to 1050kg, accommodating the needs of both busy commercial buildings and spacious residential buildings. With a rated speed range of 1.0m/s to 2.5m/s, it balances quick transit times with passenger comfort. The heart of this system lies in its sophisticated design, featuring 32 motor poles. This high pole count contributes to exceptionally smooth starting and stopping, minimizing jerk and providing a superior ride quality for passengers inside the elevator car.

Durability and protection are paramount. The motor boasts a Protection Class of IP41, safeguarding its internal elevator components against the ingress of solid objects larger than 1mm and providing drip-proof water protection. This ensures long-term operation in the demanding environment of an elevator machine room. Furthermore, with an Insulation Class of F, the motor's windings are built to withstand higher operating temperatures, enhancing its longevity and reliability under continuous use.

A key strength of the DAA20220DE model is its impressive mechanical capacity. It can handle a maximum axial load of 3,000 kg, a testament to its rugged construction and its ability to manage the significant forces present in traction elevator systems. It is recommended for a lifting height of up to 100 meters, making it perfectly suited for a variety of high-rise buildings. The fail-safe braking system is equally robust, featuring a dual-arm brake delivering a braking force between 1,560 Nm and 2,500 Nm, with a brake current of 1.12 A (at 20°C).

This OTIS traction motor operates on an S5 40% duty cycle, meaning it is designed for intermittent periodic use, which is standard for elevator operation. This includes sequences of starting, running at constant load, electric braking, and rest. This optimized operating mode directly contributes to managing the system's overall energy consumption, making it an efficient solution for modern buildings focused on sustainability. In summary, the OTIS NEOTEK 60 DAA20220DE traction machine is a cornerstone of reliable, efficient, and smooth elevator operation.
