    Hi,

    I have two 24Volt DC motors, in SMC3 I am selecting one of the modes like sinus, motors are moving, but strange thing is I can stop the motors with my bare hands, they are too weak :(
    Any idea? Thanks in advance

    Motors are removed from a used disabled wheelchair, labels are missing but the seller told me they were 24volts and 250watts.
    Arduino uno r3, IBT2

    PS: I tried to drive the motors directly through 24volt power supply, and it spins really strong that I can not resist with hand

    Check the IBT2s, members have previously reported failures, even when brand new.
