7.5.3 Relative electrical Components
Traction Gearmotor
The traction of the machine is guaranteed by an electric motor installed in combination with a gear reducer,
which acts directly on the rear wheels of the machine, ensuring traction.
With constant 24 V DC power supply (battery charged) the motor with no load (M1) absorbs 5.1 Amps
±
0.1.
With constant 21 V DC power supply (low battery) the absorption is 4.6 Amps
±
0.1.
