Claims15
An elevator lifted by a dual-motor drive apparatus, comprising:
- a car and a counterweight disposed as being lifted in a lifting space;
- a traction rope suspending the car and the counterweight;
- a traction sheave driven to perform a rotation motion by a first motor drive apparatus and a second motor drive apparatus arranged on both sides thereof, so as to drive the traction rope to lift the car and the counterweight;
- a first motor drive apparatus having a first motor and a first gear assembly;
- and
- a second motor drive apparatus having a second motor and a second gear assembly,
- wherein the traction sheave is located between the first motor drive apparatus and the second motor drive apparatus in an axial direction of the traction sheave;
- a torque generated by the first motor of the first motor drive apparatus and a torque generated by the second motor of the second motor drive apparatus are both transmitted to the traction sheave respectively via the first gear assembly and the second gear assembly, so as to drive the traction sheave to perform the rotation motion.
