Alternator Motor

Here is my recently developed sensorless motor BLDC motor controller (as seen in other videos of mine) driving a car alternator as a motor. I've provided field current by way of a variac and rectified supply and the BLDC driver is being operated on lead acid batteries.

It is closed loop.

Depending on field input current you can accomplish a lot of torque with an alternator. It depends how many poles it uses, how wide the core is, how much core material there is, how heavy the windings are and how many turns. Essentially you'll get more torque out of higher current alternators or ones that are designed to run at low speed. The limitation on torque is either where the coils heat up too much or the core saturates (too much magnetic field). Probably 20lb-ft for mine at the moment.

Closed loop?

Wow! very cool, do you know how much torque it has?
