What this combo is
The MR-JE-100+HG-SN102J-S100 is a Mitsubishi servo amplifier and motor combo from the MR-JE-_A series, paired with an HG-SN102J-S100 AC servo motor. The amplifier side is rated for 1 kW output, and the motor spins at 2000 r/min nominal. The 'J' in the motor suffix means it ships with an oil seal fitted, which matters if you're mounting it on a gearbox or a machine with oil-mist exposure — without that seal, lubricant ingress kills the bearings over time.
