YS7134 three-phase asynchronous motor

YS7134 three-phase asynchronous motor is a commonly used electromechanical product. Relatively speaking, its smaller counterpart, the YS7124 three-phase asynchronous motor, is better known. Why is that? Because the YS7124 three-phase asynchronous motor has a power of 370W, and this power level is used by more customers. However, there is a situation where most customers who repurchase the 370W motor tend to choose the 550W one, which is the product we are launching today. It has the same installation dimensions, but a higher power of 550W. In actual use, customers gradually find that the 370W power is insufficient, yet they require the same installation dimensions. Exactly, this model meets their needs. If you require dimensional parameters of other models, you can communicate with us, and we will wholeheartedly provide you with services. The motor uses copper wire, which is what customers are most concerned about. You can rest assured of this. We will dedicate ourselves to making good products, and our goal is to let consumers use cost-effective, genuine and high-quality products.
Cooling method
Self-cooling (standard configuration): The cooling method is IC411, which meets standard requirements.

YS7134 three-phase asynchronous motor is a fully enclosed self-cooling (two-way fan) type motor, which ensures sufficient cooling air volume during use. If an optional external fan is used, it is necessary to ensure a proper cooling air direction when installing the fan.
Forced cooling (optional): The cooling method is IC416, which meets standard requirements.
Motor cooling is achieved through an independent fan (forced ventilation). This type of forced cooling is not affected by the operating status of the machine.
Notes
Ensure that the independent fan has smooth air circulation and is consistent with the airflow direction of the surrounding environment; the independent fan must be powered by an independent power module, and ensure that the rotation direction of the fan is consistent with the direction indicated by the rotation mark attached to the fan cover; the independent fan cannot be driven by a frequency converter; start the independent fan first before starting the motor; when shutting down the motor, first turn off the motor power, and disconnect the independent fan drive power after the motor stops running.
Handling and storage
When transporting the YS7134 three-phase asynchronous motor, all lifting lugs must be used for handling. Before moving the motor, please ensure that the lifting lugs are installed correctly and firmly, but never use the motor shaft and fan cover to carry the motor. In addition, pay attention to avoiding swaying and vibration when lifting the motor, to prevent damage to the bearings.

If the motor is equipped with a rotor fixing device, always use this device when transporting the motor. It must remain fixed and cannot move during the entire transportation period. If the customer has installed some parts, such as a coupling or a pulley, the bearings may be damaged during transportation. In this case, the customer needs to prepare the rotor fixing device by themselves.
It is recommended that all motors be stored in a dry and dust-free environment, and avoid excessive vibration. Stacking motors during storage is not allowed. For motors with packaging boxes, follow the instructions on the packaging box.
Outdoor storage
Choose a level, stable and dry storage location. If necessary according to storage requirements, repair damaged packaging before storage. Place the YS7134 three-phase asynchronous motor, equipment and packaging boxes on a chassis, square timber or a base to prevent ground moisture and prevent the motor from sinking into the ground.

The moisture-proof cloth or rain-proof cloth must not come into contact with the surface of the stored items. Place spacer pads to ensure sufficient air circulation.
Indoor storage
It should be protected from extreme weather. The storage room should be kept dry, well-ventilated, dust-proof, frost-proof, anti-collision and anti-seismic.
Exposed metal surfaces
Considering transportation, the exposed parts (such as shaft ends, flange surfaces, center edges) have been given temporary anti-corrosion treatment (<6 months). For long-term storage, appropriate anti-corrosion measures must be taken.
The motor has been made with good materials according to the temperature range required at the time of ordering. The specified temperature range can be found on the nameplate.
Warning
If the YS7134 three-phase asynchronous motor is used or stored outdoors without any protective measures, it may cause damage to the motor.

Avoid exposing the motor to strong sunlight, rain, snow, hail or dust erosion.
Storing the motor in outdoor or high-humidity environments may cause rust on motor components. If necessary, consult the service center or follow the technical conditions for outdoor use of motors.
Storage temperature
Allowed temperature range: -20°C to +50°C
Maximum allowable air humidity: 60%
For motors with special regulations on operating status or altitude due to ambient temperature, the storage temperature must comply with other conditions. Please refer to the instructions on ambient temperature and altitude on the motor nameplate at this time.
Storage duration
Rotate the motor shaft at least once every six months to avoid fretting corrosion. Long-term storage will reduce the lubrication service life of the bearings.
Open-type bearings
When stored for more than 12 months, the grease of the open-type bearings should be inspected.
If the grease is found to be exhausted or contaminated during the inspection, the grease must be replaced immediately. Infiltration of condensed water will change the consistency of the grease.
Sealed bearings
When sealed bearings are stored for more than 24 months, the bearings at the drive end and non-drive end should be replaced.
If the motor is stored in an environment with high dust and humidity for more than 2 years, the service life of the motor will be reduced. In this case, if necessary, inspect the insulation system before installing and starting the motor to ensure its normal and stable operation (refer to 3.5 for relevant reference values).

YS7134 three-phase asynchronous motor machined surfaces (flange surfaces, shaft end surfaces, etc.) have been anti-corrosion treated at the factory, but necessary anti-corrosion measures are still required during motor storage. It is recommended to rotate the motor shaft frequently to evenly distribute the bearing grease and avoid static indentation.
