FAQ

1. Talking about the working system and working characteristics of the motor
          1 Interpretation of the motor working system
   The duty cycle of the motor indicates the allowable cycle time of the motor under different loads. The classification of the working system of the motor is a description of the load condition of the motor, which includes starting, electric braking, no-load, power-off stop and the duration and sequence of these stages. The working system is divided into 10 categories.
   
   (1) Continuous operation, S1. Continuous operation S1 is an operation with a constant load that lasts long enough to reach thermal equilibrium.
   
   (2) Short run, S2. Short-time operation is operation with load for such a short time that thermal equilibrium cannot be achieved. The interval (no voltage applied to the motor) is very long, which actually reduces the temperature of the motor to the temperature of the cooling medium. The recommended durations of short-term operation are 10min, 30min, 60min and 90min.
   
   (3) Start intermittent operation with no effect on temperature, S3. Intermittent operation S3 involves an operation consisting of a continuous sequence with the same time interval. Each of these intervals includes a constant load time and a rest time. These times, neither the load time nor the cool-down time, are sufficient to reach thermal equilibrium during this time interval, and it is assumed that the current peak at start-up does not have a significant effect on heating.
   
   (4) Start intermittent operation that has an effect on temperature, S4. Intermittent operation S4 refers to an operation consisting of a continuous sequence with the same time interval. Each of these intervals includes a start time, a constant load time, and a rest time.
   
   
   
   Neither of these times is sufficient to reach thermal equilibrium during this time interval, and in this operation, the motor is either stopped naturally after a power failure, or is braked by a mechanical brake, so that little additional heat is generated in the windings.
   
   (5) Intermittent operation where starting and braking have an effect on temperature, S5. Intermittent operation S5 refers to an operation consisting of a continuous sequence with the same time interval. Each of these intervals includes starting time, time with constant load, braking time and rest time. Neither of these times is sufficient to reach thermal equilibrium within this time interval. In this operation, braking is effected by electricity (eg reverse current).
   
   (6) Continuous operation with intermittent load, S6. Consecutive runs S6 involve runs consisting of consecutive sequences with the same time interval. Each of these intervals includes time with constant load and idle time. These times, either under load or cool down, are not sufficient to achieve thermal equilibrium within that time interval.
   
   
   
   (7) Uninterrupted operation with starting and braking, S7. Running S7 without interruption involves running a sequence of consecutive runs with the same time interval. Each of these intervals includes a start-up time, with constant load time and an electrical braking (eg by reverse current) time. Neither of these times is sufficient to reach thermal equilibrium within this time interval. There is no stall state in this operation, and the motor is actually under the action of voltage all the time.
   
   (8) Nonstop operation with variable speed, S8. Running S8 without interruption involves running a series of consecutive runs with the same time interval. Each of these intervals includes a constant load time with one of the speeds to which it belongs and a constant load time directly connected to it with the other speeds. A pole-changing asynchronous motor is an example of this type of operation.
   
   
   
   (9) Duty S9 with non-periodic changes in load and rotational speed. Under this working system, the load and rotational speed can be changed aperiodically within the allowable range, including frequent overload, and its value can far exceed the reference load.
   
   (10) Discrete constant load and rotational speed work system S10. The duty cycle includes a specified number of discrete load (or equivalent load)/speed (if possible) duty cycles, each load/speed combination should be run for a time sufficient to allow the motor to thermally stabilize. The minimum load value in one duty cycle can be zero (no load or shutdown and de-energization).
   
          2 Some other regulations on the working system
   
   In addition to being marked with the corresponding codes of S1~S10, the working system type should also meet the following requirements:
   
   For S2 working system, the working time limit should be added after the code S2;
   
   S3 and S6 working system, should add the load duration rate after the code. For example: S2-60min, S3-25%, S6-40%.
   
   For S4 and S5 duty system, the load duration rate, the moment of inertia of the motor and the moment of inertia of the load should be added after the code. The moment of inertia is the value calculated on the motor shaft.
   
   For the S7 duty system, the moment of inertia of the motor and the moment of inertia of the load should be added after the code, which are the values calculated on the motor shaft.
   
   For S10 duty system, the nominal value of the corresponding load and its duration should be marked after the code.
