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 reconnecting
them. The sMMI plug and the socket on
the cable leading to the battery must be
correctly aligned with each other when
connected. 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 breaking the cable.
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 better and
longer performance on gradients or with
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
Like all drives, gearless wheel hub motors
are also optimised with regards 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 with
a nominal drive power of 250 watts. They
achieve their highest efficiency and range in
this speed and power range which means
that the energy supplied is optimally
converted into drive energy.
