10. Output Devices

Power consumption(as group assignment)

There were not any equipments which could directly measure current value in our lab, so I calculated the value from the measured values of resistance and voltage according Ohm’s law.

Measured resistance of one motor: 5 Ohm ( 2.5 Ohm / paralleled pair)
Measured voltage of the device at working: 1.6 V - 2.6 V
Calculated current value: 0.64 A - 1.04 A ( 0.32 A - 0.52 A per one motor) (formula: I = V/R)

Manufacturer’s specications of the motor:
Model: Mabuchi FF-030PK-11160

OPERATING RANGE	CURRENT (NO LOAD)	CURRENT (MAX. EFFICIENCY)	CURRENT (STALL)
2.0 - 5.5 V	0.066 A	0.25 A	0.91 A
