This series of gearless traction machines has unique
small and long design. The traction sheaves are cantilever-mounted. Unique
design allows easy installation and removal of traction
sheaves.
The stator core is unique laminated core design without
a seat, so the machine weight and cost are reduced.
The traction machine has shaft brake with spline fit. So
the machine is exquisite, compact and small, and has better performance. This
type of traction machines can fully meet small machine room and non machine room
elevators and effectively save the space.
Accessories made by well-known international
manufacturers and imported sealed bearings are used in the traction machine,
which avoids grease change and maintenance, so perfect quality is
ensured.
