Seat Motors

There is no information in the Green Books covering 940, 960 and 850 models on stalled motor current. Generally if a motor stalls the control relay(s) will drop out to protect the circuitry. This will also happen if two motors are inadvertently selected together. I would suggest that you contact Volvo with a technical query, or measure the resistance of a motor, then divide the Voltage supply by that reading. Taking the supply as 14Volts should give a stalled motor current value very close to the actual value. I am intrigued by your reason for needing this information and would welcome the full story for the members of my registers.

Cheers, Peter.

Hi Peter I'm building a radio controlled submarine. It will use pumps to move it forward. These seat motors will provide the rotational energy for the pumps. The reason I need the amp. info. is due to the fact that I need to find a relevant battery. Regards Michael

What you need to do is find a Model shop that sells and flies electric model airplanes. They should have what is called a Whatt Meter it will measure amps at various loads to help you determine which battery setup is best for the motor and load. Astro Flight Inc. in Marina Del Rey, CA. Manufactures the meter

Sounds like a ripoff to me, just pick up a decent DMM with a 10A range, if that's not enough, get a precision 0.1 ohm resistor, put that in series with the motor and measure voltage across it, then use ohms law (simple, but there's calculators for it online too) to calculate the current.

Your 100% right James, but I was not suggesting that he buy one. Second of all, if your in the field with 3 or 4 planes, with 6 to 8 different motors and 3 to 4 different props to work with its a handy little tool to have to tune things up and get what your looking for in performance.
