*1） Power supply required is 3-phase 200/220/240/380/400/415/440V,50/60Hz. Voltage Down Transformer (Step-down transformer) is required for other voltage.
*2） Rated force of RANDOM follow the ISO5344 standard. Please contact us for further information on RANDOM force conditions of each system.
*3） Each value of specification indicates maximum power of the system. In the case of a long hours of test, it needs to be operated less than 70% of maximum power.
(The continuous use could be the cause of a premature failure.)
*4） In the case of RANDOM durability test, please set the test definition of the peak value of acceleration waveform to be operated less than 1400 m/s2.
*5） In the band of more than 2000Hz, excitation force pitches at the rate of -12dB/oct.
*6） Frequency range values vary according to sensor and signal generator.
*7） Mass and size can change in CE-support system.

Approach to low noise

Our optimised design of top cover and intake for cooling air flow which are based on fluid dynamics have much lower air flow rate and air-intake noise if compares to conventional systems.

Upper (armature) support system PS Guide

Vibration generator is given a dynamic stress by its own vibration. The Parallel Support Guide (PSG) design is a patented design to support the armature. PSG significantly improves durability and reliability of the system, and quality of vibration at the same time.

This compact design provides enough stiffness which exceeds such function of roller support system and realized high durability and self-holding supporting system by alternative alignment of gears that have a unique curve.

World’s largest class air cooling system

Combination of magnetic circuits based on finite element analysis, the optimized magnetic circuits and cooling technologies has brought large air cooled system (54kN) to this i-series. The air cooling system of IMV eliminates the initial costs and maintenance trouble inherent in a water cooling system.
