MT32-IND-PWR
Installation of coil for inductive powering on shaft
2x1 LAGER (Standard)
Attach for electromagnetic insulation “Ferrite
Tape” 2 x one layer around the shaft.
Fixed with 2 layers mounting tape
Wind the 0.50…0.63 mm enameled (CUL) copper wire
around the shaft:
7-25 windings for 1000-20mm diameter
Other diameter on request!
Note: “The inductive load of the MT- IND-PWR and the
capacitor in the Power Head must be in resonance to
get the optimal transmission. The inductive load of the
shaft depends of diameters, material and number of
windings. ”
To find the optimal transmission try 1-2 winding more or
less. The LED on the inductive power module will help
to find the best configuration. The distance between
power-head and the coil is 3-10mm.
Control the output voltage and move the power-head in
the max distance to the coil.
The minimum output voltage must be 5 V!
Fix all with 2-3 layers around the coil with mounting
tape.

Installation of coil for inductive powering on shaft
2x1 parallel and 1x over parallel LAGER (can reach larger distance)
Attach for electromagnetic isolation “Ferrite Tape” 2x parallel and
1x in the middle over two layer around the shaft
Make power coil with 5-25 windings for 1000-20mm diameter (see diagram) and twisted the end of wire.
Use 0.5 …0.63 mm CUL wire (Enamelled copper wire)
Strip the isolation from the end
of the wire with a skinning tool or
head up you soldering iron over
450°C to burn off the insulation
from the wire!

MT32-IND-PWR Installation of the power head for inductive powering
The pins “AC IN” are the AC power input from
the coil. On the pins “+5” and “GND“ you get a
stabilized output voltage of 5V DC. The
control LED will lights up, as soon as the
power head is switched on and at the right
position - close enough to the coil on the
shaft.
The max. load current on the DC output is
500mA. (depends of diameter and distance)
The AC/DC converter will use instead battery
pack!
Never use any battery pack together with the
MT32-IndPwr!
Connect the power head on the “AC Out” socket of the
power box and then the DC power cable on the “DC In
10-30V” socket. The two banana plugs have to be
connected to a DC power source with red on +10-30V
DC and black on 0V.
You should mount the power head at a fixed location
that it’s as free as possible from vibration influences.
The center of the coil should be in the same horizontal
position as the center of the power head. The distance
is optimal in the range between 3 and 10mm. (depends
of shaft and current consumption)
If the red LED of the AC/DC converter lights up, the
position of the power head is OK.

Don’t use for mounting any kind metal
in this area (25-30mm)! Otherwise flow
magnetic energy in the metal also and
degrease the distance between power
head and coil (on shaft)!

Safety notes for inductive powering
The device should only applied by instructed personnel.
The power head emits strong magnetic radiation at 60 kHz to a distance of 20 cm.
Therefore persons with cardiac pacemakers should not work with this device!
Magnetic data storage media should be kept in a distance of at least 3m from the power
head to avoid data loss. The same is valid for electromagnetic sensitive parts, devices and
systems.
Do not place the power head in the switched-on state on metallic objects, because this
results in eddy currents which could overload the device and strong heat up small objects.
Also the probe could be destroyed!
No metallic objects, other than the disc-type coil, should be located in the air gap of the
power head. The same applies to metallic parts within a radius of up to 15–20 mm in all
directions.
Do not use damaged or faulty cables!
Never touch in the area between shaft and inductive head, the rotating shaft itself or rotor
electronic contacts during operation!
This is a “Class A” system suitable for operation in a laboratory or industrial environment.
The system can cause electromagnetic interferences when used in residential areas or
environments. In this case the operator is responsible for establishing protective
procedures.
