Re: Treadmill motor torque
The MC-60 is also a triac controlled bridge, except it also includes current limit/ ramp up features etc of which the el-cheapo versions do not..
The better versions are PWM such as MC2100 but these also have non-adjustable current limit, ramp up etc.
For a DIY PWM drive , it generally requires some intelligent controller such as Microchip or Arduino etc .
The advantage of DIY you can incorporate Bi-directional use and RPM indicator etc.
