General selection criteria to find the correct
TORCMAN
Presently engines with four different diameters (stator diameters 28, 35,
43 and 68.5mm) are available with up to four different stator lengths (from
5 to 40mm) - in total 12 different sizes. They cover the power range of
approximately 50 - 4000W and allow to find a suitable motor for almost any
application of electrical models from the
Slowflyer to the large Scale Model, from the Mini-Heli to
High-Performance Helicopter.
The rotation speed of each type of engine can be adapted within a wide range
(4000 - 16000 U/min) by variation of the number of winding turns.
Particularly for the electrical flight the tuning of propeller, battery and
engine plays an extremely important role, so this flexibility is a big
advantage of the used engine principle.
For applications which require higher revs (10000 - 16000 U/min), in
particular for helicopter drives, the 10-pole engines have proven to be
the better choice, since they turn about
30% faster than the 14-Pole versions. Therefore, all engine sizes are
available as both 10- and 14 pole versions, except
the Monster (TM685) .
New in TORCMAN's product portfolio are
outrunner motors with planet gears. They allow a by factor 2 to 3
increased power throughput with the same motor size and bigger prop sizes,
while weight and size remains reatively small. Of course the use of high
precision and high efficient planet gears from Reisenauer drives up
the price, and therefore these drive sets should only be used where directly
driven outrunners cannot compete.

clicking this link The following table shows, that the motor windings
have extremely low impedance, since about 25% of the engine weight are
allotted to copper in the coil.

The exact
outside dimensions can be found under the column Motors of the
respective types.
Dependent on the model weight and desired motorizing, a rough selection of
the engine size (type) is the first step. Also the type, size and number of
battery cells mostly accompany with the size of the model. Under the column
Configuration - Wing Models or Helicopters you find an
overview of the most usual model types and the suitable engine sizes. Our
practical samples on the website show a lot of successful application
examples from our customers and may help you selecting the correct drive set
for your model.
The diameter of the TM280 series is about 35mm, and so it fits well
into slim fuselages of small models. Depending on the length of the stator
(5, 10, 15 and 20mm) the power ranges from 50 to 350 Watts. With sufficient
cooling also far higher power is possible for short time.
The diameter of the TM350 series is 42mm and fits thus well into most
fuselages with 42 to 44mm front frame. Three lengths are available for
selection with a power range from 250 to 900 Watts.
With the geared version, the mounting rib and spinner can be reduces down to
38mm.
If power above 800Watt is required, the TM430-20 or TM430-30
should be selected. It covers the range upto 1800Watts and has an outer
diameter of 52m. Of course one can, if available, select the next longer
version to have sufficient reserves for future models.
If this still isn't sufficient, it's time for the Monster (TM685).
This huge motor is available in 3 lengths and allows to drive with upto
4000Watts really big props upto 28"diameter. appropriate controllers are the
Jeti Spin99 (685-20) and the Spin200 or Kontronik Power Jazz for the
TM685-30 and -40.
As rule of thumb is considered:
-
for electric
glider models and slow Scale models approx. 100 to 150 Watts of input
wattage per kg model weight is recommenden, for big scale gliders with
SLS-System 80 - 1000Watt is sufficient.
-
for sportive
gliders 150 -250Watt/Kg allow easy take off by hand and fast climbing
-
for Hotliners
and motor models approx.. 200 - 400 Watts per kg, depending on expected
flight performance and engine running time, for dynamic acro flight, 200 -
250Watts are fine.
