EMT

Electromagnetic Force Dynamic and Fatigue Testing System

Test force	1 – 5 kN
Test type	Tensile, bending & compression tests
Drive	Electromagnetic
Type	Floor-standing appliances
Industries	Dynamic

Allows Long Stroke Lengths and Fast and Highly Accurate Testing in a Clean Environment

High-Rigidity Frame

A very rigid loading frame is used that resistant to resonance is used.

Large Testing Table (EMT-1kN)

A larger testing table allows testing of even large samples. Lifting/lowering the crosshead can provide a testing space large enough to install a thermostatic chamber.

Capable of ±20 m Displacement Cycles at a 200 Hz Frequency (EMT-1kN)

Fatigue tests can be done at high frequency, which can signi cantly reduce the overall testing time.

Achieves Stroke Lengths from 0 to 100 mm (±50 mm)

The system can be used for large-displacement and high-speed fatigue testing of rubbers. It also supports tensile and compression testing.

EMT-1kN

EMT-5kN

A dual-stage drive mechanism enhances safety.

Dual type and light resistant test

Due to the large testing space, tests can be performed inside a thermostatic chamber.

1. Actuator

The electromagnetic actuator is coupled with low-friction bearings to achieve high waveform reproducibility.

2. Electric Crosshead Drive and Manual Clamp Levers

The crosshead can be raised or lowered using an electric switch. The crosshead can be immobilized easily using manual clamp levers.

3. Load cell

4. Emergency stop switch

5. Servo Controller 4830 and Control/Data Analysis Software

The controller allows high-performance and high-functionality dynamic and fatigue testing.

6. Power Amplifier Unit

Internal electronic power circuits are used to drive the electromagnetic actuator. The top surface can be used as a table for the controller.

Dual-Stage Crosshead Drive Mechanism

Using two buttons to operate the crosshead and clamps helps prevent operating errors and accidents.

8. Air-cooling unit (inside main unit)
