Work schedule and technical data：
1 The rated voltage of the motor is 380V and the rated current is 50Hz.
2 The motor is suitable for intermittent periodic load. According to the different nature of the load, the working system of the motor is divided into:
（1）Intermittent periodic work system (S3)：
It is a series of identical duty cycles, each cycle includes a period of constant load operation and a period of stop and power-off (see the figure below). In this type, the starting current of each cycle should be free from the temperature rise of the motor. Obvious impact; every 10 minutes is a duty cycle, i.e. six starts per hour
N Operating time under rated conditions
R Stop and de-energize time
Qmax The maximum temperature reached during the working cycle
load duration
CDF=
（2）Intermittent periodic duty with start (S4)：
It is a series of identical working cycles, each cycle includes a start time, a constant load operation time and a stop and power-off time (see the figure below); the number of starts per hour is divided into 150, 300 and 600 times.
D start time
R Stop and de-energize time
N Operating time under rated conditions
R Stop and de-energize time
Qmax The maximum temperature reached during the working cycle

（3）Intermittent periodic duty system with electric braking (S5)：
It is a series of identical working cycles, each cycle consists of a start time, a constant load operation time, a fast electric braking time and a stop and power-off time (see the figure below).
D start time
N Operating time under rated conditions
F Electric braking time
R Stop and de-energize time

3 When selecting a motor, various starting and braking states need to be converted into equivalent full starts per hour according to the equivalent heat generation. Determine the rating of the motor based on the number of equivalent full starts. Typical examples of conversion are shown in the table below.
Way of working | Braking state | Thermal Equivalent Start Times |
starts per hour | Number of jogs per hour | Brakes per hour | Number of brakes and reverses per hour |
S3 | 6 | 0 | 0 | 0 | 6 |
S3 | 4 | 8 | 0 | 0 |
S3 | 2 | 8 | 2 | 0 |
|
S4 | 150 | 0 | 0 | 0 | 150 |
S4 | 100 | 200 | 0 | 0 |
S5 | 80 | 0 | 80 | 0 |
S5 | 65 | 130 | 65 | 0 |
S5 | 30 | 160 | 30 | 30 |
S4 | 300 | 0 | 0 | 0 | 300 |
S4 | 200 | 400 | 0 | 0 |
S5 | 160 | 0 | 150 | 0 |
S5 | 130 | 160 | 130 | 0 |
S5 | 60 | 320 | 60 | 60 |
S4 | 600 | 0 | 0 | 0 | 600 |
S4 | 400 | 800 | 0 | 0 |
S5 | 260 | 0 | 320 | 0 |
S5 | 260 | 520 | 260 | 0 |
S3 | 120 | 640 | 120 | 120 |
Conversion method: Four times of jogging (the final speed does not exceed 25% of the rated speed) is equivalent to one full start; one electric brake (braking to 1/3 of the rated speed) is equivalent to 0.8 full starts.

The data on the nameplate of the motor is generally provided according to the reference working system. If the user has special requirements, the data will be provided according to the user. When the motor needs to operate in a way other than the S2~S5 working system, it is necessary to negotiate with our company.

The shaft extension of the motor can be manufactured according to the size or requirement proposed by the user. Transmission mode: The motor is driven by a coupling or a spur gear. If a spur gear is used, the minimum diameter of the pitch circle of the gear should not be less than twice the diameter of the shaft extension. The motor stator outlet box is located on the top of the motor, and the wires can be outlet along both sides of the motor, and the rotor can be outlet from both sides of the end cover.
