eDrive - Summer 2017 - 19

CoMponents
In addition to drive technology, chokes from SMP are used
in industrial applications in power electronics, automation
and signal processing, in railway technology, electromobility,
maritime and medical engineering, for renewable energies
as well as for conventional energies, and in the aerospace
industry. The components are designed for currents up to
3,000 A and frequencies up to 500 kHz, in special applications even up to 2 MHz. SMP uses powder composite materials that have been developed and manufactured entirely
in-house and feature lower eddy current and magnetic
reversal losses. The materials have a high saturation induction of up to 2 Tesla. The components can be manufactured
with dimensions ranging from 19 mm to 300 mm, weighing
from 0.05 kg to 130 kg, and up to temperature class H (up
to 180°C). Depending on the application, protection classes up to IP66 are available. All components are
RoHS and REACH compliant and CE and EAC certified and the materials used are UL-listed.

Quantum Devices, Inc. Model QDH20 provides an improved feedback solution in applications typically
using a standard size 20 package. The QDH20 provides encoder feedback in standard industrial
mounting configurations with superb mechanical and environmental protection. Outputs consist of a
quadrature A & B with reference pulse Z as a standard feature. The output can be configured with either
the industrial standard 5 to 26 volt OL7272 line driver or open collector outputs. The QDH20 features
two heavy-duty bearing sets holding the output shaft, and two more bearings along with an integral
flexible spring mount to isolate the working pieces of the encoder from mechanical stresses.
