eDrive Test System for Electric Motor and Inverter Analysis

HBM Inc. has introduced a solution for eDrive testing, a powerful, integrated system for measuring the performance and efficiency of electric motors and inverters.

• Completely integrated test solution that allows engineers to record, verify and study both electrical and mechanical parameters under dynamic conditions
• Combines HBM’s T12 or T40 torque sensor, the GEN3i data acquisition system, and as an option the Quantum 1609B temperature satellite to provide synchronous, dynamic and continuous acquisition of mechanical and electrical signals from an electric drive system
• Makes temperature, torque and rotational measurements
• Able to take measurements from as many as 18 current and voltage channels at voltages up to 1,000V, at a sampling rate of up to 2 MS/s
• Incorporates intuitive eDrive software GUI developed exclusively for electric motor and inverter testing
• Optional high voltage 2-wire shielded cables with safety banana connectors are provided in various lengths for noise immunity and improved signal integrity
• Optical Ethernet interface offers complete display and control from a remote location or control room via an external PC for additional safety from high voltages and currents
• Mechanical torque and rotational signals are recorded by the use of a rotating torque sensor with an integral slotted disc for speed sensing
• Provides raw data, as well as real-time analysis
• Includes software that provides a complete characterization of an electrical drivetrain
• Software analyzes raw data and displays real time results, such as true, reactive and apparent power and efficiency calculations, and allows for more extensive verification and analysis of the corresponding raw data
• Freely programmable formula database can be used to determine equivalent circuit diagrams, calculate air gap or cogging torques for motor analysis plus calculation for space vector, part transformation and THD to analyze inverter behavior
