Schottkey flyback diode for motor advice please.

    I will soon wire up a 36 Volt 80 Amp permanent magnet DC motor to be
    run at 48 VDC. It will be used in a homebuilt trike.

    I am looking for a flyback diode that will take the full current during

    slowdown when the power is turned off by a contactor (no PWM).

    I would appreciate knowing whether to use a single diode, series
    diodes, a Schottky, a series resistor, etc.

    What is the most cost effective solution?
