treadmill permanent magnet DC motor as generator

Very few people in the world can generate that much power (.8 HP) and only for a few seconds. Most folks are more like 1/4 Hp or 200 watts.

thanks for the info, so that means the voltage during the amp test was around 15v. so back to my idea, the motor is a 2HP motor. 1500W ?? so running off a pulley from a 2 stroke lawn mower, can i use an ordinary PWM charge controller? would the voltage output vary with the load from the batteries?

not sure what the Vdc was in the amp reading. the 10 amp i maintained for a few seconds didnt want to fry my cheap multimeter. the specs of the DC motor are 3400rpm 220Vdc 6.5 Amps. so its a 1400W motor? would the voltage output of the motor be constant with a given RPM? when i produced 10 Amps the RPM felt like about the RPM i had at about 10-20Vdc

You rock dude ! 10A @ 60v is 600W you are a super mega athlete.

picked up a treadmill from the kerb, connected a multimeter to the motor and walking on the treadmill produces more than 60Vdc very easily. in the amp setting i could feel the load and had no trouble getting 10 amps with moderate effort. just wondering if i rigged it up to an old lawnmower what charge controller would i need to use as a 24v battery charger? i will post some pics or a video of the treadmill producing current 2mor
