New three in one portable motor tester saves time and money

Ideal for both the electric motor repair shop or on the production line, the new ‘Motatest’ from Whitelegg Machines combines the three main tests that previously would be carried out by individual instruments. Thereby speeding and simplifying analysis and testing. 

The 12V, battery powered, Motatest will surge test windings to identify inductance problems, measure their resistance to confirm balance and flash test the windings to identify earth faults. This allows the engineer to make the fundamental decision about a motor of whether to overhaul or rewind. 

When on the production line the Motatest's ability to compare against preset values and tolerances makes is ideal for pass/fail verification by non-skilled operatives.

The standard 'L' Model offers the ability to carry out automatically a surge test, resistance test, open circuit test and short circuit test Results are compared against pre-installed limits and a pass or fail decision given on the condition of the winding.

 These results can then be downloaded via an RS232 port to computer for storage. These tests can also be carried out manually for more detailed investigative work. The resistance test is accurate to milli-ohms as the Motatest can circulate up to 1.4 amps in the test circuit.

Additionally the higher spec. ‘X’' Model offers a 4000V-dc power source that can automatically carry out polarisation index tests or for speed a shortened one-minute DAR test. It can flash test at any pre-selected voltage and time duration automatically and display the resultant leakage current or insulation resistance.

 The XL Model also comes with probes and software to check induction, neutral point, Hall effect rotary field and magnetic field strength and direction.

The unit's 12V rechargeable battery gives a very long life even when carrying out repeated resistance tests. With an entry price of £1920.00 and the ability to test up to 250-300Kv motors, the Motatest is a unique and very versatile tool, ideal for any work place.

In any repair or production environment, time is of the essence. Maintenance engineers are always looking for ways of making a job easier to tackle or quicker to complete, or both. So, when rapid test, diagnosis and essential repair is time-critical, and where physical access to motor equipment is limited, Whitelegg’s new three in one portable motor tester provides the answer.

Motatest is part of a family of mains and battery powered precision portable testers available from electric motor maintenance specialists, Whitelegg Machines – a company that has been supplying test equipment to the electric motor repair and production industry for over 25 years.

With the stringent condition monitoring requirements of today’s maintenance engineers in mind, the company has introduced a range of compact, rugged and fully portable on-site test equipment units for motors up to 250kW.

Offering workshop accuracy, speed and reliability, these instruments cover the entire spectrum of surge, resistance and insulation fault detection in the most timesaving and cost-effective way.
