Troubleshoot direct-on-line motors while in service, without mechanical sensors—so you don’t sacrifice uptime.
The 438-II Power Quality and Motor Analyzer can help troubleshoot power quality problems in three-phase and single-phase power distribution systems, while giving you the mechanical and electrical information you need effectively evaluate motor performance.
- Measure key parameters on direct-on-line motors and motors driven by voltage sourced inverters (VFD) including torque, RPM and mechanical power
- Calculate Mechanical Power and Efficiency without the need of mechanical sensors, while the motor is in service using three-phase input measurements
- Perform dynamic motor analysis by plotting of motor de-rating factor against load according to NEMA guidelines
Fluke 434-II, 435-II and 437-II users can add these great motor analysis capabilities and features to their existing analyzers today with a product upgrade option. Existing 438-II users can upgrade their firmware to include the variable frequency drive enhancements at no cost on the Fluke website.

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
