STGIPS30C60 30A IGBT bridge & 15mΩ shunt for the 1.5kW Induction Motor Speed Controller
These parts can be used to build, upgrade or repair the 1.5kW Induction Motor Speed Controller.
The main part is the STGIPS30C60 hybrid three-phase IGBT bridge module. The originally specified part is the STGIPS20K60 and this is rated for 18A continuous current and 40A peak.
By comparison, the pin-compatible STGIPS30C60 is rated at 30A continuous, 60A peak. So this should make the speed controller more rugged and better able to withstand overload before the protection circuitry kicks in.
We're also supplying the 15mΩ 6332 (2512) SMD shunt, rated at 3W.
Note that if you want to use these parts to repair a damaged controller, chances are that IC2 (LM319; Jaycar ZL3319, Altronics Z2520) will almost certainly need replacing.
It's also possible that some or all of the high-speed opto-couplers (OPTO1, 4N35 & OPTO2-3, HCPL2531) could be damaged so check them too.

1.5kW Induction Motor Speed Controller PCB [10105122]
PCB for the 1.5kW Induction Motor Speed Controller.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay. Includes routed holes (unplated) for access to heatsink mounting screws.
This is the updated version of the PCB which addresses the reliability problems that some constructors experienced. Specifically, some high-current/high-voltage tracks were routed away from the control portion of the IGBT hybrid module to prevent interference. See the article in the December 2012 issue (link below) for more details.
200 x 125mm.

dsPIC33FJ64MC802-E/SP programmed for the 1.5kW Induction Motor Speed Controller [1010512B.HEX]
A dsPIC33FJ64MC802 16-bit digital signal controller with motor control peripheral, programmed with the firmware for the 1.5kW Induction Motor Speed Controller (1010512B.HEX).
This is the updated version which fixes a couple of bugs, lowers the over-temperature threshold and adds a shortened boost mode (activated by placing a jumper over pins 3 & 4 of the ICSP socket). See the article in the August 2013 issue for more details.
