Usage environment
1. The altitude shall not exceed 1000m
2. The ambient temperature ranges from -15 �� to 40 ��.
3. There is little ash in the surrounding medium, no ferromagnetic material dust, no corrosive metal or insulating gas, and no explosive gas.

Loading, unloading, and storage of CF series speed measuring generators
1. The installation of the speed generator rotor should have a diameter that matches the specifications of the installation shaft. The keyway must be straight and flat, and the magnetic pole should not be struck. When dismantling, special tools should be used to pull out the 2-M5 screw hole.
2. When connecting the lead wire of the speed generator and the excitation winding, attention should be paid to the outgoing line markings. The three-phase of the speed generator is U, V, W, and the excitation winding is F1, F2.
3. When the speed generator is stored for a long time or deemed necessary, the stator should be dried before installation, and then other insulation resistances should be checked to ensure compliance with requirements.
4. The speed measuring generator should be stored in a ventilated and dry environment, and there should be no corrosive gases in the air.

quality assurance
If the speed generator is damaged or cannot function properly due to manufacturing quality within one year of user use, our factory will provide free repair or replacement. Excluding those damaged, dismantled, repaired or modified by users during loading and unloading.

Common faults and their troubleshooting

serial number	fault phenomenon	reason
one	Three phase voltage imbalance	1. The output end is not firmly pressed or has poor contact 2. The DC resistance difference of the three-phase winding is too large 3. Short circuit in a certain part of the winding 4. Broken line somewhere	Check the outlet end and tighten the nut tightly Replace the stator Column replacement stator Connect the broken wire or replace it
two	puncture	1. Winding insulation damage 2. It has been confirmed that it has been severely affected by moisture 3. Incorrect experimental method	Replace the stator Dry first, then check Test according to Table 2
three	Low output voltage	1. Low residual magnetic induction intensity on the rotor surface 2. Severe axial misalignment of rotor and stator magnetic poles 3. Load bias or partial short circuit	Re magnetize or replace the rotor Check and adjust the axial installation dimensions Adjust the load and check the circuit

Ordering Instructions
1. In addition to indicating the product model, the order should also provide the rotor aperture size. For example, "CF-2-32" refers to a speed generator with a stator stop diameter of �� 135mm and a rotor aperture of �� 32mm. Or provide the center height dimension of the speed motor seat.
2. Speed generators with different installation dimensions and external dimensions from those listed in Table 1, or with changes in their main performance parameters, are products with special requirements. When ordering, in addition to indicating the model, specific special requirements must also be provided in detail. And leave a certain delivery time.
