Motor, Perm PMG-132SKU: 1690
Regular price $2,498.00
We're often asked if these motors are still in production, or if we can really supply them, and related parts. Yes, we've never had a supply problem. We re-stock and ship them regularly. See possible lead-time notes below.
PERM PMG-132 is a 24 to 72 Volt Axial Flux Motor. Similar in size and weight to a Briggs & Stratton ETEK (no longer in production) and early LEMCO Motors, but more powerful. 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 ships as a neutrally-timed, brushed, permanent magnet DC motor. The armature is made of flat copper strips stacked together so there's no stack of steel lamination's like in a traditional motor which gives the motor low cogging. Its high power, high efficiency, and comparably small size make it an excellent choice for small electric vehicles, Electrathon vehicles, Shell Eco-Marathon hybrids, generators, go-karts, and robots.

There is a red arrow sticker on the motor case indicating shaft rotation direction when polarity is connected as specified. The manufacturer does not address the efficiency nor peak limits when operated in reverse. If motor brush timing is advanced from neutral for efficiency purposes in the marked "forward" direction, then the reverse direction will usually be less efficient. It is possible to adjust the motor timing to optimize for the application, within the mechanical limits of the case slots. Brush and commutator life may be affected differently when running in reverse full time.
