The eDrive solution from HBM acts as both a power analyzer and data acquisition system. It has the ability to record ALL signals along the drive train (power source, inverter, torque and speed of a motor, temperatures, CAN signals, strain, vibration, etc.) with a single instrument. This greatly reduces the test complexity and results in synchronous measurement of all parameters.

Power and efficiency calculations are performed based on digital cycle detection which enables accurate calculations even under very dynamic conditions, when the fundamental frequency of the inverter may be changing very quickly. Digital cycle detection also means that mechanical power is calculated over the same cycle as electrical power, resulting in more accurate efficiency measurements. Finally, digital cycle detection greatly reduces the required measurement time per set point when creating, for example, a motor map. This results in data for a full motor map being recorded in minutes rather than hours or days.

Having access to the raw data allows engineers to understand what happened without having to run additional tests. Best of all, the eDrive provides accurate, real-time results quickly.

Free seminars in select locations

If you are interested in expanding your knowledge of electromechanical power conversion, HBM will be hosting some FREE seminars in select locations. This opportunity allows test engineers to ask questions and review project ideas directly with a motor and drive system specialist. In these seminars, you will:

• Learn the fundamentals of electric power and magnetics
• Study basic machine fundamentals for DC, induction and synchronous motors
• Learn the basics of inverter theory and design
• Discuss best practices for making dynamic motor measurements
• See live demonstrations and analysis for improving machines and drives

Upcoming dates and locations:
April 20, 2018 in College Park, MD
May 8, 2018 in Milpitas, CA
June 26, 2018 in Southfield, MI

Seating is limited! Other seminar dates and locations will soon be added so be sure to check back later for a seminar near you. Register for a seminar today by clicking here.
