Wheel Motors (5-1-5); Blade Motor (5-1-6) - Husqvarna Automower 305 Technical Manual

5.1.7 Blade motor
The blade motor is a highly effective brushless
motor of the three-phase type. The nominal rotation
speed for optimum mowing results is 2,900 rpm.
The nominal output of 20 W delivers a satisfactory
performance even with demanding types of grass.
The motor cannot be repaired and must therefore be
replaced if it is defective.
5.1.8 Wheel motors
The two wheel motors are of the brushless DC
motor type. This guarantees a long service life and
minimal maintenance. The motors are supplied as a
unit together with gearbox, wheel motor end cover,
gasket, hub and cable.
Right and left wheel motors are identical (and
consequently have the same article number as spare
parts).
The motors cannot be repaired but are replaced as a
unit.

5.1.9 Charging station
Automower 305,308 and GARDENA R40Li,
®
R70Li are charged with direct current (in contrast
to alternating current for the Automower
models). This means that it is very important
to always connect the plus and minus cables
correctly to the charging strips on the mower and
the contact strips in the charging station.
The F signal is generated in a so-called single
turn antenna.
The robotic lawnmower is guided all the way into
the charging station by the guide signal, which
means that additional signals (besides A, F and
Guide) are not needed.
The cabling in the charging station is connected
to a contact strip that is connected to the charging
station's circuit board. The cabling in the charging
station is supplied as a unit.
