埃及采购需求：发电机

I am in the market for a generator and would appreciate your assistance in finding the right one for my needs. Specifically, I'm looking for a generator with a minimum power output of 40 watts. It's crucial that the starting torque is 0.01 N.M or even lower, as this will greatly influence the overall performance. Additionally, I'd like the generator to operate within a speed range of 150 RPM to 550 RPM. If you could provide recommendations or options that meet these specifications, along with any relevant details about their features and benefits, I'd be very grateful. Looking forward to your guidance on this!
