During high-speed rotation of the motor, it is prohibited to apply brake by directly
short-circuiting the terminals. But in case of emergency, terminal short-circuiting is allowed at
zero-speed startup in order to move the car up and down slowly for the purpose of rescuing.

2.1 Product Construction
WYJ140 series permanent-magnetic synchronous gearless traction machine (hereafter called
traction machine) adopts the low-speed, high-torque permanent-magnetic synchronous 3-phase
motor which provides direct way of drive. Therefore the product has the advantages of low
power consumption, low noise, free of pollution and little requirement of maintenance. Its main
construction characteristics are:
l
The traction sheave side adopts double-row self-aligning roller bearing
l
The adopted permanent magnets and the dovetail groove are fixed to the external circle
surface of the rotor by high strength adhesive in order to ensure that during the operation
course, it will not demagnetize or peel off even if the rotating torque exceeds 2.5 times of the
rated torque.
l
The brake system consists of two sets of independent working armature, friction disc,
electromagnet and brake releasing micro-switch.
