Overview
The GLV-40S1 series machine is a synchronous permanent magnet gearless machine
designed for elevators. The machine has 30 poles to provide smooth, quiet, and long-lasting
operation. Its configuration allows elevator capacity up to 4000 lbs. with 1:1 roping, single wrap
arrangement at 50% counterbalance with up to a 22000 lb. shaft load. See Section 4.4 below
for complete specifications. The overall system load is calculated by adding the following
items:
Empty Car Counterbalance Ca Hoist Rope
Compensation Traveling Cable Weight
The GLV-40S1 machine brake system uses four block brakes.
The latest HWEC manuals, bulletins and procedures are available for download from the
HWEC website.
The following is a list of major components of the GLV-40S1 machines. Along with a
description of their functions, there is an overview of some of the critical adjustments and
maintenance information. See Installation and Maintenance for detail.
1.
PM Motor Housing
- The housing contains the PM windings used to provide the
necessary torque and speed to move the elevator in operation.
2.
Traction Sheave
– A grooved sheave is connected directly to the machine rotor. The
grooves provide traction between the sheave and the hoist ropes.
3.
Brake
– The electromechanical device is used to prevent the elevator from moving
when the car is at rest.
4.
Sheave Guard/Rope Retainer
– Provides rope retention and keeps hoist ropes away
from contact after rope installation.
5.
Machine Rotor & Brake Wheel
– The brake wheel is connected to the main shaft.
When the brake is energized, the brake is released from the brake wheel.
6.
Nameplate
- Displays the machine rated data and manual factory contact/serial
number information.
7.
Encoder
– (Behind Cover) This device is directly coupled to the rotor of the machine. It
is provided to give the absolute speed feedback of the hoist motor to the inverter drive
system and to the elevator controller
