Technology Center-->Detailed structure and principle of vibration motor

The structure and principle of the vibration motor are described in detail:
The vibration motor consists of a special motor plus an excitation weight. When the motor is energized and rotated, the excitation block generates an exciting force, and the vertical and horizontal vibration machinery is transmitted through the motor foot or the flange.
The special motor consists of special sub-line package and rotor shaft, which can withstand high-frequency vibration. The horizontal vibration motor uses four fan-shaped eccentric blocks as excitation blocks to adjust the angle between two eccentric blocks on the coaxial end, which can be from zero to Zui greatly adjusts the exciting force of the vibration motor; the vertical vibration motor uses two eccentric blocks as the excitation block, one at each end of the shaft, the upper shaft end is a fixed eccentric block, and the lower shaft end is an adjustable eccentric block. A set of additional blocks are arranged on the outer sides of the upper and lower eccentric blocks, and the exciting force of the vibration motor can be adjusted stepwise by adjusting the number of the additional blocks.
The vibrating motor is energized and rotated to drive the eccentric block at both ends of the motor shaft to generate an inertial exciting force, which is a spatial rotating force, and its amplitude is Fm.
Fm=mrω2
M-eccentric mass
R-the distance of the center of mass of the eccentric mass, that is, the eccentricity ω-motor rotation angle frequency ω=2πn/60
n—Vibration motor vibration inertia excitation force is transmitted to the vibration machine through the vibration motor bearing, foot or flange, which is the exciting force generated by the vibration machine.
3. The vibration motor should be stored in the outdoor, the indoor air should be dry, no bad gas, the temperature should be 5C above the dew point, the relative humidity should not exceed 50%, and the motor should be kept flat. When storing, the vibration motor should be properly maintained. Turn the rotor shaft of the motor several times a month, and periodically check the vibration motor for rust and moisture.
4. Installation of vibration motor The vibration motor and the vibration mechanical connection plane are all processed with a 6.3-smooth finish. The flatness should meet the 9-level tolerance requirements of Table 1 of GB1184-79. The strength of the foot mounting or flange mounting bolts must not be less than 8.8. The vibration motor must be firmly mounted on the vibration machine. The foot or flange bolts should be secured with a locking device. When tightening, tighten the torque to the following torque:
M12 88Nm M30 1350Nm
M16 200Nm M36 2600Nm
M20 390Nm M42 3600Nm
M24 680Nm
After the vibration motor starts to run for 20 minutes, it should be stopped for inspection. Use a torque wrench to check the tightness of the foot or flange bolt. If there is any shortage, it must be tightened according to the above requirements. The above procedure should be repeated after two hours of operation. Repeat the check of the strength of the foot or flange bolts every two to four hours in the next two days, and then check every four to six weeks.
Note: The robust torque of the vibration motor mounting bolts and the inspection procedure are very important for the protection of the motor. Damage to the vibration motor is often caused by improper mounting bolts.
