    Will this still work with a more powerful motor?

    Is it direct drive at the moment, presumably you do not require high speed, if so look at a geared motor solution, your torque will increase by the ratio of the reduction and the power requirement will be the same or lower. M.

    Shaded Pole Fan Motor - Speed Control Question

    The light dimmers they have at H.D. are just about the same as the fan motor variety, the latter usually has a suppression choke or other noise suppression features. The Triac is usually rated for something higher than a simple lamp. M.

    Shaded Pole Fan Motor - Speed Control Question

    You could we be affecting the optimum phase shift caused by the shading ring, if so you could cause extra heating. M.

    Shaded Pole Fan Motor - Speed Control Question

    That is not going to work. Also the stator is designed to work with the shading ring for phase control so you also could upset this arrangement. I would open the 'dimmer' and replace the switch with a pot. M.

    Shaded Pole Fan Motor - Speed Control Question

    You should be able to get full range control with a proper Triac 'Dimmer' control. Do you mean it didn't go over 25%? M.

    16X2 LCD display problem while measuring AC current

    Ensure you DC is decoupled properly with sufficient capacitance across the supply. Using an isolated supply for the LCD and low voltage circuitry may help. M.

    We have to interface load cell with Plc

    I was thinking more on the lines of the manuf add-on that would be an expansion module of the PLC, many manuf offer different option modules for different interface solutions, this then communicates directly with the PLC memory. M.

    power ground and signal ground

    It is done quite frequently in industrial control electronics where the DC power common is connected to earth ground, this however is commonly done with a star ground point, and/or something called equi-potential bonding, this is ensuring that all metallic parts are bonded to avoid ground loops...

    16X2 LCD display problem while measuring AC current

    You most likely need better decoupling of the LCD supply, or galvanically isolate the LCD circuit from the AC power. Is the relay switching the Lamp? Whatever is switching it, a R/C snubber across the switching element may work also. M.

    We have to interface load cell with Plc

    Check to see if your manuf of PLC has a 4-20ma add on module or unit. Most load cells use this communication method. M.

    Operating something when furnace fan is on

    I don't think that one is entirely suitable, there are basically two types one that just switches on detection of current, and one used for measuring actual level, you really need the former. M.

    There is also a non invasive way using a Honeywell current sensor in a motor conductor. See CSDA series. M.

    Operating something when furnace fan is on

    Is this a Gas or electric furnace? There is usually a relay or a small transformer energized when the thermostat picks up. You could wire a relay off of this maybe. Generally there is a schematic in one of the furnace doors. M.

    How many Amps can my transformer deliver?

    3.6a at 15v. The use of electrolytic's also increase the Va requirements of a supply. M.
