Sponsored by HBM Test and Measurement Mechanical power measurements of an electric machine are very important to help understand what the motor is doing at any given time and operating point. Mechanical measurements help characterize the motor, build up models for the machine, ensure confidence in controllers, and understand the limits of the system. Measuring torque with high accuracy, bandwidth, and… Read more »
Measurement technology specialist Hottinger Baldwin Messtechnik (HBM) has announced that its T40MS torque transducer, intended for testing electric drives and transmissions, is now available as a cost-optimized solution. The T40MS is suitable for high-speed measurements up to 30,000 rpm. It covers the available nominal torques of 500 Nm, 1 kNm and 2 kNm in a… Read more »
Sponsored by HBM Test and Measurement In-vehicle testing provides engineers with a method to benchmark competitors’ vehicles, calibrate drivetrains, and validate the performance of the product. In the emerging electric vehicle market, electrical power measurements on motors and inverters are becoming necessary to evaluate the powertrain of the vehicle. Previously, mobile power measurements were difficult due… Read more »
HBM eDrive is a system for testing electrical inverters and electrical machines. Mechanical signals (e.g., torque) and electrical signals (current, voltage) are acquired simultaneously, helping to better understand the electric drive and its losses in minutes. This is important for the optimization of the drive as well as the increase in efficiency. In contrast to… Read more »
Sponsored by HBM 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… Read more »
