Vibration Motors Precision Microdrives

Vibration Motors Precision Microdrives

There are two basic types of vibration motor. An eccentric rotating mass vibration motor ERM uses a small unbalanced mass on a DC motor when it rotates it creates a force that translates to vibrations. A linear resonant actuator LRA contains a small internal mass attached to a spring, which creates a force when driven. As specialists in the supply and design of vibration motors, you can ...

MOSFET Drivers Microchip Technology

MOSFET Drivers Microchip Technology

MOSFET drivers are beneficial to MOSFET operation because the high-current drive provided to the MOSFET gate decreases the switching time between the gate ONOFF stages which leads to increased MOSFET power and thermal efficiency. Our diverse array of MOSFET drivers supports a wide range of applications ranging from DCDC power supplies to a ...

Variable Speed Drives an overview ScienceDirect Topics

Variable speed drives VSDs, also called variable frequency drives, are a valuable tool for the energy manager. Typically the VSD system consists of a three-phase AC induction motor and a variable frequency power supply. The variable frequency power supply uses solid state components to produce a pulse-width modulated current that varies the ...

An Introduction to Machinery Vibration

An Introduction to Machinery Vibration

An Introduction to Machinery Vibration. In simplest terms, vibration in motorized equipment is merely the back and forth movement or oscillation of machines and components, such as drive motors, driven devices pumps, compressors and so on and the bearings, shafts, gears, belts and other elements that make up mechanical systems.

Vibrational Issues Machine Service Inc

A torsional vibration is a twice per revolution vibration. A torsional vibration will cause the drive shaft, downstream of the front U-joint, to speed up and slow down twice per revolution. That means that a power supply producing a constant speed of 3,000 RPM can actually be attached to a drive shaft that is changing speed ...

The operation under VFD control shows high amplitude at 60 Hz center frequency and sidebands at 49.87 Hz from the center frequency. The 49.87 Hz is the same frequency at which the torque shows the highest oscillating amplitudes see Figure 2.5. The contrast between VFD operation and across-the-line operation is the lack of sidebands in the ...

Electric Motors and Drives in Torsional Vibration Analysis

The electrical drives are composed of an electric motor and its electric supply system. Thus analysis cannot always be lim-ited to the electric drives but have to be extended over the whole electric drive from the shaft-end to the electric grid in-cluding the optional frequency converter. In order to predict the vibration behaviour of any torsional
