You are watching: Can i use a 6v adapter for 9v
I have actually seen some basic comments online about running a 6V DC motor on 9V Battery gift OK. I am looking to run an waiting mattress pump originally designed for 4x 1.5V D battery (6V DC) native a universal automobile laptop adapter. The lowest calculation voltage top top the auto adapter is 9V.
Nothing ~ above the wait pump motor mentions input strength specs specifically. The only markings I can see room the following 3 lines and I obtain no hits googling each string.hb-138-101 rs-380ph-6016rb 630301
The alternate would it is in to use an AC inverter and also an DC 6v 2A adapter. The sounds choose overkill to walk from 12v come 120v AC just to acquire 6VDC, but so is running a automobile engine. Will certainly I burn the motor if i ran it on 9V DC?

6v from 4 turn off D batteries will certainly be 6volts or less, not 6v or more, when driving a reasonable load.
Depending exactly how much friend paid for the pump (so exactly how well make it\"s most likely to be), the commutator sparking, the bearings rattling, the windings and brushes over heater are simply a couple of of the noticeable wearout instrument that would certainly be exacerbated by overabundance speed, voltage and also load. The lifetime at 9v might be hours, or may be minutes. Space you emotion lucky?
Look top top Amadong or fleaBay and find a DC come DC converter the does go down to 6v, they\"re not expensive. Cheaper come buy one before you ruin the pump rather than after, and also another pump.

According come Mabuchi Motor\"s chart,
\"rs-380ph-6016\" is the designation for a carbon brushed \"380\" size motor v 16 transforms of 0.6mm wire. To compare this come the \"3-12V\" RS-380PH-4045 which has actually 45 turns of 0.4mm wire. Motor speed is inversely proportional to the number of turns, so your motor is probably rated for less than 6V. In ~ 9V that will try to turn 50% faster and also draw around twice as lot power. If the 9V adapter deserve to handle this climate you risk burning out the motor.
The ideal solution is a 6V \"switching\" regulator rated for sufficient current. A D cell is an excellent for about 2A max, so hopefully the motor draws no much more than 2A ~ above 6V and something like this must do the job.
