Whether for new elevator systems or modernization projects, the OTIS DAA20220DY traction motor represents the perfect combination of innovation, sustainability, and engineering excellence—providing long-lasting performance and eco-friendly operation that aligns with today’s energy-saving standards and urban mobility demands.

The OTIS DAA20220DY Traction Motor exemplifies OTIS’s commitment to innovation, energy efficiency, and reliability in the field of vertical transportation. As one of the most advanced gearless traction motors in the OTIS lineup, this model has been meticulously engineered to meet the demands of modern high-rise, commercial, and residential elevator systems, where precision, safety, and performance are paramount.

At its core, the DAA20220DY uses a gearless permanent magnet synchronous motor (PMSM) design, which eliminates the need for traditional mechanical gears. This direct-drive configuration ensures smoother operation, reduces mechanical losses, and enhances overall efficiency. With fewer moving parts, the motor operates quietly and requires significantly less maintenance than conventional geared traction systems. This design improvement not only reduces service downtime but also extends the system’s operational lifespan, resulting in lower long-term costs for building owners and operators.

One of the standout features of the DAA20220DY is its energy efficiency. The PMSM technology enables high torque generation at low energy consumption levels, making it ideal for sustainable building projects. By minimizing power loss and optimizing current flow, the motor contributes to lower energy bills and supports environmentally friendly elevator operation. This efficiency is particularly beneficial for buildings aiming for green certifications, such as LEED or BREEAM, as it reduces both operational costs and the overall carbon footprint.

The compact and lightweight design of the OTIS DAA20220DY offers installation flexibility in both machine-room and machine-room-less (MRL) configurations. Its streamlined structure saves valuable building space and allows architects to design more efficient elevator shafts without compromising system performance. Despite its compact size, the motor delivers high torque density, ensuring excellent traction even under heavy loads or frequent usage.
