Features of vibration motor: 1. The matching of excitation power and power is appropriate, with large vibration force, light body weight, small size, low mechanical noise, and mechanical seal. 2. Because the vibration motor is a strong impedance type vibration rather than resonance, it has a stable amplitude. 3. Wide range of vibration frequency. The vibration frequency of electromagnetic vibrator is fixed, generally equal to the power supply step rate, while the vibration frequency of vibration motor can be adjusted in a wide range by adjusting the speed, and can arbitrarily choose vibration frequency and amplitude according to different purposes. 4. Less affected by power fluctuations. The excitation force of electromagnetic vibrator will change greatly due to voltage variation, but this change is very small in vibration motor. 5. Multi-machine combination can realize self-synchronization and complete different process requirements. 6. The direction of exciting force can be changed according to the installation mode of vibration motor. 7. The exciting force and amplitude can be adjusted infinitely only by adjusting the angle of eccentric block. 8. Maintenance is simple. Since the spring is not used like the electromagnetic type, the maintenance work such as clearance adjustment, weight adjustment of vibration motor can be exempted, and only regular maintenance of bearing is required. 9. Complete specifications can meet the working needs of all kinds of vibrating machinery.
