Soft Starting Crane Three phase Asynchronous Electric Motor , YSE Series
soft boot motor, soft starting motor, Conic rotor motor
Detailed Product Description
l,YSE series soft boot is the newly designed electric motor with the characteristic of soft starting. It is specially designed to meet the working requirements of lifting cranes, such as a variety of single and double girder overhead bridge cranes, portal gantry cranes, trolleys running mechanisms, to provide the driving force. It is also suitable for the travelling of electric hoist.The motor has a soft start feature, no need to connect starting resistance, "soft start" effect is achieved without taking any other measures. The motor itself comes with a flat-friction brake, brake, with adjustable breaking speed, so that effectively reduce the crane "impact" phenomenon at starting and stopping.
380V, 50Hz, AC, 3-phase
Basic Duty: S3-40%
Insulation Class: F, H
Frame size: 112mm-280mm
2,The motors will operate normally under the following conditions:
(1) temperature of coolant not exceeding 40℃(for crane uses) or 60℃(for metallurgical uses).
(2) Altitude form sea-level not exceeding 1000m.
(3) Frequent and significant mechanical vibration and shocks.
(4) Frequent starting ,braking(electrical or mechanical) or reversing.
3. The rated frequency of the motor is 50Hz and rated voltage is 380V.
4. Connection : for motors with power of 132KW or below, Y type connection;T others: △ tye connection. Motors using Y connection can also add zero wire.
5. Type codification.
6,Output and speed
The range of rated output and ,asynchrouons speed for the basic duty type (S3-40%) are shown in table 1.

There are eight type of duty type for these series motors ,S2, S3, S4, S5, S6, S7, S8, and S9, The basic duty type is S3—40%, Cduty type is S3 cyclic duration factor is 40%, each cycle is (10min), The following duty types are most useful for these series motors.
1. Short times duty type (S2)
Operation of constlant load dring a given time, less than that required to reach themal equilibrium followed by a rest and de-energized period of sufticent duration to re-establish machine temperature withir 2 deg K of the coolant (sec figl).
2. Intermittent periodic duty type (S3)
A sequerce of identical duty cycles, each including a period of operation at constant oad and a rest and de-energized period (see fig2) but the operation period are so short that it is not sufficinet for the machine to reach themnl equilibriun in this duty type, the cycle is such that the starting current does not significanten affect the temprature rise.
3.Intermittent periodic duty type with starting (S4)
A sequence of identicae duty cycles, each including a sisnificnnt period of starting, a period of oreration of constant load and a rest and de-energized period (see fig3), but the operation periodsare so short that it is not sufficient for the machine to reach thermal equilibrium.
4. Intermittent period duty type with electric braking (S5)
A sequence of identica duty cycles, each consisting of a period of starting a period of operation at constant coad and a rest and de –energized period, but the opertion period are so short that it is not sufficient for the machine to reach thermal equilibrium (see fig4), but the operation periodsare so short that it is not sufficient for the machine to reach thermal equilibrium.
Application
The ranges of applications
This series of motors are specially designed for service on cranes and hoists. They can also be used for similar applications such as material handling, weirs and sluices, and lifts of all types. These motors can serve as auxiliary motors in rolling mills or wherever intermittent drives are required.
Design features:
l,Degree of protection Frame 160-400 IC411 3, Construction and mounting arrangemens are shown in table 5. |

4,Insulation class
5,Terminal box of the framse.
6,Type of drive the pitch diameter of the pinion should not be less than twice of that of the shaft extension.
7, Brush holder and brush latest design so that the pressure between the collector ring and brush can remain unchanged while the brush are worn out during operaton. The type of brushes used is J201 and size sare shown in table 6. |
