    ECM Identification

    I am trying to determine an easy way to identify ECMs. I've been told that fractional horsepower ECMs will usually include a designation in the motor model number indicating motor type and motors greater than 1HP usually say ECM somewhere on them. Is this correct? If not how are they identified?
