Demonstration video

As a demonstration of the Magtopressor™ capabilities, a unit designed as substitute for reciprocating air compressors is compressing air into a 16bar 5Liter tank
Published on Last update on

During the test, the stator is supplied with a single phase 50Hz AC voltage. The applied voltage is progressively increased during the test to maintain oscillation amplitude at a desired value (voltage-controlled variable displacement drive) while the pressure in the 5L tank is increasing.

The test scenario consists in filling-up the tank from a 0 bar to a 10 bar relative pressure.

Air Magtopressor™ Demonstrator Characteristics

With dimensions of (LxWxH in mm) 273x140x151.5 and a weight of 7.76kg, the Air Magtopressor™ Proof of Concept is sligtly smaller (in volume) and lighter in weight than comparable State of the Art reciprocating compressors

Air Magtopressor™ Demonstrator Test Setup

The Air Magtopressor™ Proof of Concept Test Setup aims to evaluate the performance of the Magtor Linear Drive by using air as the brake mechanism (motor load). Although designed as a test bench for the Magtor Linear Drive it effectively ends up as an “air compressor demonstrator” for the Magtor Linear Drive.

Characteristics of the Application Side (e.g. diameter of pistons) will define the operational capabilities of the Magtopressor (e.g. Air Flow vs Air Pressure, motor load, …) while the Demonstrator Test Setup will define maximum reachable pressure below which tests are stopped for safety reasons (e.g. tank, pressure gauge and digital pressure sensors go up to 16 bar).

Graphs for Air Flow (in liter-per-minute), AC Power Supply (in Watt) and Temperatures (in °C) as functions of the Air Pressure (in bar) as recorded during test are provided below for an up to 12 bar relative pressure within the tank:

During the test, the supply voltage is progressively and automatically increased to maintain a fixed oscillation amplitude while air pressure in the tank is raising.
