No one has posted about this subject so far, so here is my electric lawnmower.
The motor was from an early Simpson (Delta 10, Simpson 14* to 277). It is wired to high speed.
I have found that it is a bit gutless power wise but will cut grass no problems. I have also found that 4 blades cuts better than 2 blades but one day I will make 6 blade machine to see how that cuts. It is not battery powered but uses a long lead so care must be taken not to cut it.
The blade disc is held by an adaptor shaft to fit on the motor shaft to the disc. It is of the length to make the blades the same position as when they were petrol driven.
I have converted 3 lawnmowers using these motors and I also converted one using a Maytag motor. The Maytag motor is a better, stronger motor than the Simpson motor.
The beauty of this conversion is that the mower runs when then power is there. It is quieter and less hassles than petrol.
The only problems I have had was a broken lead wire and if you try to cut too high grass you will stop the motor rotating and this could lead to overheating. The motors do have thermal overload protection built in on the start circuit, so if it does overheat and you stop the motor rotating then it won't start again until it cools off enough.
