will be not enough. If too much, the oil will be leak out.

23
Geared Traction Machine Operation And Service Manual

If the machine storage more than 1years, the oil should be

changed before use.

When using mineral oil, the first time oil changing should be

done after the new machine runs 400 hours. If using synthetic oil,

it should be done after 700 hours running.

After that, depending on the machine running condition,

changing mineral oil each 2000-3000 hours (at most 12-18

months) and synthetic oil each 3000-4000 hours (at most than

24—36 months). For good results, the first time recommend

using mineral oil. But please note that it is forbid to mix mineral

oil and synthetic oil. If changing the mineral oil to synthetic oil, it

should be operated as following steps:

a. Take off the rope when machine stops then drain the

mineral oil away.

b. According to machine oil, pour kerosene to geared box.

After running with high speed little, drain the kerosene away.

Repeat 2 or 3 times.

c. Pour synthetic oil as require.

4.2 Brake system maintenance

There are two micro switches install in the brake system used to

feed back the acting of brake, we recommend customer to

connect them to your control system.

Surface temperatures of brake may occur >100 °C. For this

reason, no temperature-sensitive parts such as normal cables or

electronic components may be routed to or fixed to the braking

surface. Provide appropriate protection against accidental contact,

if necessary.

Because the running situation is deferent, we can’t control the

adjusting time. So the operator who in charge of maintenance

45
Geared Traction Machine Operation And Service Manual

works should inspect the running situation regularly. Normally,

every month should be inspected.

When doing any inspection or maintenance work, make sure that:

a. No inadvertent starting of the motor is possible;

b. No load moment is acting on the brake drum or on the

motor;

c. After completion of the inspection and maintenance

work, the interlocking preventing inadvertent starting of the

motor is cancelled

d. All surfaces providing friction are free from oil or

grease; it is not possible to clean an oily or greasy brake

lining.

4.3 Brake system adjustment

Before adjust the brake system be sure that the car is no

passenger and the car must at terminal station and the

counterweight must on the buffer.

Check the brake wheel and the brake shoe clearance,

when the minimum clearance more than 0.4mm, or brake safety

travel only 0.5 mm, both as long as to meet the one, should be

adjusted.

Method: hand push the brake guide shaft or hit the

cap, measure the gap “A” in guide shaft and bolt.

Since the mechanical structure of each model is slightly different,

there are two methods to measure the brake spring compression:

1. Without ruler in machine (as shown in the left picture below),

measure the free length of the spring and the compressed length

with the ruler, and then subtract the two length values to calculate

the compression amount of the spring.

2, Have a ruler in machine(as shown in the right below), you can

read the spring in the free state and compression state of the scale

value, the spring compression amount is the subtraction of the

two values.

5 Three-phase asynchronous motor

5.1 Overview

5.1.1 YTTD series

YTTD series 3-phase regulating speed induction motors are

developed for special purpose applications in elevator.

Motor’s insulation is class F, motor’s rated voltage and frequency is

380V 50Hz(motor’s rated voltage and frequency is 380V 60Hz for

machine YJ410) with single winding, motor runs on intermittent

periodic duty (S5) with intermittent rate of 40%, 180 starts per hour.

There are two kind poles of 4 poles 、6 poles and 8 poles.

Motor’s mounting type is flange installation structure, additional

positive temperature coefficient thermal resistance protector can be

imbedded in the stator winding upon client’s request so as to

effectively keep motor from burn out caused by likely locked rotor,

overload, improper and low supply voltage, etc, because a optimal

68
Geared Traction Machine Operation And Service Manual

combination of thermal resistance and thermal protector can

accurately and instantaneously monitor the temperature variation of

motor and switch power supply off at once when the designated

temperature has been reached.

High performance motors specially designed can meet the actually

operating condition and environment requirements of

adjustable-frequency equipments and elevators. They can start at

high starting torque with low staring current and operate at low slip

with low noise and vibration.

5.1.2 YTD series

YTD series 3-phase AC induction motors available with double

speeds are developed for special purpose applications in elevator.

There are two classes of insulation B and F, motor’s rated voltage and

frequency is 380V 50Hz with double winding, 6(4) poles for high

speed setting and 24 (16)poles for low speed setting.

69
Geared Traction Machine Operation And Service Manual

Motor runs either on intermittent periodic duty (S5) with intermittent

rate of 40%, 180 starts per hour, 3 minutes duration for 24(16) poles

running, or on equivalent short time duty (S2) with 30 minutes

duration for 6(4) poles rate running and 3 minutes duration for 24(16)

poles rate running.

Motor provide an alternative mounting type of horizontal installation

(B3) or flange installation (B5).

High performance motors specially designed can meet the

actually operating condition and environment requirements with

high starting torque and low staring current, low noise and

vibration.

5.2 Basic performance

Please refer to nameplate of motor.

5.3 Operation instruction

1. Check and ensure that all connecting bolts at outside of

70
Geared Traction Machine Operation And Service Manual

motor are securely fastened.

2. Ground terminals in terminal box must be connected to

appropriate earth with appropriate cord, securing grounded

well.

3. Measure the dielectric resistance between windings and

frame with megger whose scale up to 500 MΩ, need to dry

motor prior to be used if less than 1MΩ.

4. Conduct wire connections based on wire diagram.

5. Check and ensure firstly that line source conforms to

specification and mount and connections meet this manual’s

requirements, then switch motor on if all are okay.

Check and ensure that motor operate smoothly and no desirable

noise.

6. YTD series Motors must start with 6(4) poles windings for

normal operating condition. When overhauling elevator, motors

must start and run on 24(16) poles setting within 3 minutes

running.

71
Geared Traction Machine Operation And Service Manual

5.4 Maintenance

1. Motor should be inspected and maintained periodically

together with elevator. The relevant details must be written

down and kept carefully.

2. The motor permits reasonable slight and harmonious sound

during operation. Motor must stop at once to check and replace

worn bearings if abnormal noise caused by bearings has been

found out.

3. Motor must be dried off when the dielectric resistance

between windings and frame is less than 1MΩ. A locked

rotor current method is recommended to do drying treatment,

that is, letting motor operate at locked rotor status on

50~60VAC 50Hz power supply. More care should be given

to ensure that locked current is less than rated value,

windings temperature rise not over 70K.This task must be

done by expertise personnel.
