(Excitation force ~ 140kN)
1 Theme content and scope of application||tt ||JB5330---91
This standard specifies the terminology, basic parameters, technical requirements, test methods and inspection rules, and marking and packaging requirements for three-phase asynchronous motors with vibration sources (hereinafter referred to as vibration motors). This standard applies to general-purpose vibration motors with a rated exciting force of 1 to 140kN. Other special types of vibration motors can also be implemented by reference.

3.1 Rated vibration force
When the voltage and frequency of the power supply are rated, the eccentric block of the vibration motor is at the specified position, The vibration force generated by the self-excitation of the moving motor is expressed in lower Newtons.
3.2 Rated excitation power
The power corresponding to when the voltage and frequency of the power supply are rated and the vibration motor outputs the rated excitation force. 3.3 The installation dimensions of vibration motors are divided into two types: type A and type B. Type A: It is recommended to use a structure where the mounting feet are connected to the end cover. Type B: It is recommended to use a structure where the mounting feet are connected to the machine base. When there is no distinction between type A or type B installation dimensions, it is represented as either structure. 3.4 Vibration motor model
The vibration motor model consists of three parts: product code, specification code and supplementary code, and is arranged in the following order. The Ministry of Mechanical and Electronic Industry of the People's Republic of China approved the implementation on 1992-07-01 on 1991-06-28

Specification code
The product code is selected by each manufacturer and reported to the model issuing unit for filing. Supplementary code
The specification code consists of the rated excitation force of the vibration motor (Arabic numerals expressed in lower Newtons) and the number of poles (Arabic numerals) in sequence and separated by dashes.
The supplementary code indicates that the vibration motors are of the same specification, type A or type B, and the installation dimensions are in capital letters. Example: YZU-10-4B
indicates that the rated excitation force is 10kN, 4-pole type B YZU series vibration source three-phase asynchronous motor with installation dimensions, type, basic parameters and dimensions

5.11 The vibration motor should be able to withstand the vibration resistance test of 1×10° vibration times. Check that the vibration motor should have no abnormal phenomena and can continue to operate normally
The test is when the acceleration the vibration motor outputs the rated excitation force withstands is not low Carry out under the condition of 6 times acceleration of gravity. 5.12 The vibration motor adopts Class B insulation. When the altitude and ambient air temperature and filtration meet the requirements of Article 5.2, the temperature rise limit of the vibration motor (resistance method) of the winding is 80K, and the allowable temperature of the bearing (thermometer method) should be Not exceeding 105 (. 5.13 The vibration motor should be able to withstand the maximum torque value (taking into account tolerance) specified in Article 5.6 of this standard in a thermal state and with gradually increasing torque for 15 seconds without a sudden change in speed. When the vibration motor rotates and harmful deformation occurs, the voltage and frequency should be maintained at the rated value. 5.14 When the eccentric block of the vibration motor is at the specified position of the rated exciting force, the vibration motor should be able to withstand an increase in rotation speed of 105% of its rated value. 2 minutes without causing harmful damage. 5.15 The end of the stator winding of the vibration motor should have anti-vibration measures, and the fasteners used should have anti-loosening measures. 5.16 The insulation resistance of the stator winding of the vibration motor should be in the hot state or after the temperature rise test.
