How to assemble the vibration motor to maximize the vibration frequency?
How to assemble the vibration motor to maximize the vibration frequency, each pole and each phase coil of the vibration motor will bear, theoretically, the vibration frequency of the vibration motor can be considered in this way.
(1) The vibration frequency of the vibration motor is equal to the vibration frequency of the rotor mass due to the unbalanced state, and the vibration frequency of the vibration motor is equal to the actual vibration frequency of the rotor.
(2) The amplitude of the amplitude vibration motor is affected by factors such as the circumferential direction of the bearing, the circumferential direction of the bearing, the flange, the mounting bracket, etc., which directly affects the size of its vibration.
When the vibration frequency of the bearing and the center of gravity of the rotor and the eccentricity of the mounting bracket or bearing seat are relatively low, the motor should generally adopt semi-hard transmission, and the amplitude of the vibration motor is less than or equal to the mass of the rotor body.
(3) The amplitude value is based on the amplitude value measured by the shaking table, mm, and the maximum allowable value is 2.5mm/s, of which: 2.5mm/s In order to prevent the interference of solid noise and dust, dust-proof, dust-proof, Moisture-proof and other measures to minimize the noise it produces. For the measured numerical simulation of the shaking table, the real numerical simulation is the simulated real numerical value, which is relatively complicated, but it is difficult to simulate the measured numerical value with general numbers.
(4), digital vibration table (StopActiveFrequency)
The emergence of digital shaking table, in order to reduce the impact on the equipment during mechanical vibration, the digital shaking table adopts the method of digital filtering, on the premise of improving the accuracy and speed of the system, The results show that the vibration frequency range of the digital shaking table is very wide, and can reach 1Hz~40Hz, and its dynamic response speed can reach 10~20ms.
