Gearless drive system for elevator doors combines safety and versatility

  • Gearless drive system for elevator doors with high ride quality and low noise emission
  • Versatile solutions for doors weighing up to 280 kilograms
  • Single-button commissioning halves time required for installation
  • Integral sensor unit in motor provides a high level of safety

Siemens is extending its Sidoor range with a gearless drive system for elevator doors. The Sidoor ATE500E model introduces EC (electronically commutated) technology to the Sidoor lineup for the first time. Its new gearless EC direct drive requires less maintenance and exhibits less wear than DC (direct current) drives.

The result: a longer service life, improved energy performance and reduced operating costs. Sidoor ATE500E delivers short door opening times and rapid acceleration ramps of up to 3,000 millimeters per second squared (mm/s²). The gearless drive system from Siemens also offers a high dynamic response, excellent ride quality and high holding torque coupled with low noise emission and motor heating.

Thanks to "single-button commissioning", Sidoor ATE500E can be set up quickly and easily too – with an automatic training journey to complete the process. This ensures incorrect settings are avoided. The motor in the drive system, which is compatible with doors weighing up to 280 kilograms, can even be used in different orientations.

The gearless drive system provides a high level of safety thanks to an integral sensor unit in the motor that monitors operating data. Sidoor ATE500E also features a temperature sensor that records the heat generation of the drive so that the motor can be operated close to the thermal load limit, for example, and still be protected against overloading. Another sensor, this time a high-resolution magnetic unit, records information related to the angle of rotation. The position of the door is measured via an incremental position encoder simulation. The Sidoor FOC (Field Oriented Control) control concept optimizes the motor speed in a closed-loop procedure, moreover, to ensure high control quality independent of weight. An intelligent diagnostics unit additionally carries out an automated function test prior to every journey, which improves efficiency. The proven circuit logic provides additional protection for the electronic systems in the event of exposure to external forces.

Sidoor ATE500E is uncomplicated to install; indeed Siemens has taken care to simplify the process of retrofitting old systems with an innovative screwless enclosure concept. The optional Sidoor software kit simplifies application and offers detailed parameterization and diagnostics. The new gearless drive system is versatile enough to be used with a range of different communication interfaces, for example with a CAN or relay module.
