5.3.2.17 Information on the sMMI plugs
If you need to remove the sMMI plugs
leading to the battery, please observe the
following information when connection
them again. The sMMI plug and the socket
on the additional cable to the battery must
be correctly aligned to each other when
connecting. Both parts are quite hard to
connect, this, however, prevents moisture
ingress during operation. Do not bend
the attached cables by any means when
connecting the plug and the socket! There
is a risk of cable break.
5.4. Thermal management
A combination of three temperature
sensors, an intelligent software control
and patented air circulation ensure optimal
cooling of the motor. This means: more and
longer performance at gradients or in case
of heavy (trailer) loads.
Advantage:
protection against premature overheating
in case of long gradients or heavy loads -
longer assistance on hills, higher efficiency
and thus lower battery consumption since
the motor is optimally cooled.
About the theory
As all drives, gearless wheel hub motors are
also optimised with respect to an operating
point consisting of speed, load and power.
Our wheel hub motors are designed for
operation in the speed range between 15
km/h and 25 km/h and a nominal drive
power of 250 watts. They reach the highest
efficiency and range in this speed and
power range which means that the supplied
energy is optimally converted into drive
energy.
