PWM electric drives

Pulse width modulated control of electric motors

Very popular fields of application for the LTT24 include real-time key figure acquisition from electric motors (e-mobility and power tools), standard-compliant EMC measurements, performance data measurements in the production of photovoltaic cells and ultra high-resolution image sensor measurements in observatories; it is also used in the development of bio sensors and the construction of test benches for turbochargers and airbags as well as in the defense industry etc.

The fields of application are so diverse for good reason: the unbelievably low distortion of the highly synchronously sampled measuring inputs allows mathematical statements of unprecedented quality. The LTT24's capabilities for the pulse width modulated (PWM) control of electric motors are of particular interest in this context. The physics behind this take place in the steep switching edges in which the LTT24 acquires sufficient measurement data to precisely determine all the key performance indicators.

With a resolution of 24 bits and a sampling rate of up to 4MHz per channel, the up to 16-channel LTT24 is perfect for precise and fast measurement requirements.
