DAA20220AK OTIS Elevator Traction Motor

The OTIS DAA20220AK Traction Motor is a premium, gearless elevator drive system engineered to provide smooth, quiet, and energy-efficient performance. Manufactured by OTIS Elevator Company, a global leader in vertical transportation, this traction motor is designed for modern residential, commercial, and high-rise elevator systems. Utilizing advanced permanent magnet synchronous motor (PMSM) technology, it delivers high torque, precise speed control, and exceptional reliability with minimal energy consumption. The DAA20220AK’s compact and lightweight design allows for flexible installation in both machine-room-less (MRL) and traditional elevator setups. Built from robust materials and equipped with superior cooling and control systems, it ensures consistent operation even under heavy load conditions. Its low noise, vibration-free performance, and low maintenance needs make it ideal for modern, high-performance elevators. Combining innovative design, sustainable efficiency, and long-term durability, the OTIS DAA20220AK Traction Motor represents OTIS’s dedication to safety, reliability, and the future of smart vertical mobility solutions.

The OTIS DAA20220AK Traction Motor stands as a testament to OTIS’s long legacy of excellence and innovation in elevator engineering. This advanced gearless traction motor has been meticulously developed to deliver unmatched reliability, efficiency, and smooth operation for modern elevator systems installed in commercial buildings, residential complexes, and high-rise structures around the world. It embodies the company’s ongoing mission to enhance urban mobility through safe, energy-efficient, and intelligent elevator technologies.

At the core of the DAA20220AK lies gearless permanent magnet synchronous motor (PMSM) technology. Unlike traditional geared motors, the PMSM design uses powerful magnetic fields to generate torque directly on the drive sheave, eliminating mechanical gears. This direct-drive system dramatically reduces friction, mechanical wear, and maintenance requirements while enhancing efficiency and smoothness. The result is a quieter, vibration-free operation that ensures exceptional ride comfort for passengers—an essential factor in today’s high-end and high-traffic buildings.

The DAA20220AK traction motor is specifically engineered for energy-efficient elevator systems. It offers superior power output with lower energy consumption, helping building owners reduce operating costs and environmental impact. This energy performance aligns with green building standards and contributes toward achieving certifications like LEED (Leadership in Energy and Environmental Design). When paired with OTIS’s ReGen™ Drive system, the motor can recover and reuse energy generated during braking, further improving energy savings and reducing waste.

Designed with a compact and space-efficient structure, the OTIS DAA20220AK can be easily integrated into machine-room-less (MRL) systems or conventional machine room setups. Its streamlined design optimizes shaft space and installation flexibility, allowing architects and engineers greater freedom in building design. Despite its smaller size, the motor provides high torque density, supporting elevators with heavy loads and multiple stops while maintaining consistent performance.
