It is possible a couple of other motors from the P5 series might fit depending on your application: the 400W is 113mm long x 70mm square, the 500W is 126mm long x 86mm square (these are untested: check the dimensions of the space inside your machine first!!) If you try a different P5 series motor, make sure to get one with an S in the part number (incremental encoder), no brake, and no gearbox.
Some other specs on the P50B07030VXKS7: max rpm 3000, 300W output, torque ???
