Product Overview
The WYT-T Series uses a permanent magnet synchronous motor and an outer-rotor structure. Eliminating the conventional gearbox reduces transmission loss and helps provide high torque density, low vibration and quiet elevator operation. Its compact axial profile supports efficient machine-space planning.

Frequently Asked Questions
Is the WYT-T1.5A a gearless traction machine?
Yes. It uses a permanent magnet synchronous motor and does not require a conventional gearbox.
What elevator capacity and speed does it support?
The standard WYT-T1.5A configuration is rated for a 450 kg load and 1.5 m/s speed with 2:1 roping.
Can it be used for elevator modernization?
Yes, when its mechanical dimensions, traction conditions, electrical parameters, brake, encoder and inverter are compatible with the existing elevator system.
What should be confirmed before ordering?
Confirm the rated load, rated speed, roping ratio, traction sheave diameter, rope quantity and diameter, shaft load, brake voltage, encoder, inverter and installation dimensions.
Important Selection Note
Final product selection must be verified against the complete elevator design and applicable project requirements. Contact ZH-ENG Engineering with the elevator specifications for configuration confirmation.
