Accurate Analysis of the Drive Using Raw Data

Many Components, One Measuring System

With growing awareness of the causes and impacts of climate change, vehicle emissions are under closer scrutiny. Both business and private vehicle owners are re-considering how vehicles are powered – and growing numbers regard electric drive vehicles as the best choice for their mobile future.

To continuously improve the efficiency of electric motors, Bertrandt Ingenieurbüro GmbH in Wolfsburg, Germany tests the drive components of electric vehicles for their customers. The Bertrandt Group offers services related to all aspects of the product development value-added chain for the automobile and aviation industry. Over 11,000 employees stand for future-proof solutions at 46 locations in Europe, China and the USA. This development service provider has been using the eDrive testing solution from HBM for tests on electrical components such as electrical machines and inverters since mid 2014.

The goal is to achieve the best setting for the motor. Important factors to consider include better efficiency, higher maximum power and optimized handling. Up until recently, Bertrandt has used a traditional power analyzer design for static operating points, to determine a characteristic efficiency diagram. However the disadvantage to that is is  it does not save  raw data nor the calculated values over an extended period of time. With the new measurement system from HBM, that's all history. Raw data is supplied synchronously and displayed quickly – and we can save it with automatic trigger control," says Max Bernholz, Team Leader of E-Drives Testing at Bertrandt.
