Perm Motor PMG 132

This is it, folks. The bigest, baddest motor we've ever seen under 25 pounds!  The bigger brother to the PMG 080, it is similar in size and weight to a Briggs & Stratton ETEK, but at the same voltage it has a 50% higher peak power output, a 40% higher torque constant and 120% more stall torque.  The PMG 132 is a "pancake" style neutrally-timed, brushed, permanent magnet DC motor manufactured by Perm Motor in Germany.  It is similar in design to the Lynch/LEMCO LEM-200 and Briggs & Stratton ETEK motors.  The armature is made of flat copper strips stacked together so there's no stack of steel laminations like in a traditional motor which gives the motor low cogging.  Its high power, high efficiency and comparably small size make it a good choice for small electric vehicles, electrathon vehicles, generators, go-karts and robots.  The motor's body is 222 mm (8.75") in diameter and 120 mm (4.72") long.  The shaft is 19 mm (0.748") in diameter and 43 mm (1.69") long with key and threaded hole.
