What this servo motor brings to the line
The Mitsubishi HG-SR352BJK is a 200V class servo motor from the MELSERVO-J4 series, built for applications that need a sealed, high-resolution motion package. The IP67-rated enclosure means the motor body handles washdown and airborne particulates directly on the machine frame — no secondary cover needed. That's a real advantage on food, beverage, or packaging lines where hose-down cleaning is routine. Inside, the 22-bit absolute encoder gives 4,194,304 pulses per revolution, shared between absolute and incremental modes. That resolution supports tight position hold without homing on power-up, as long as the battery-backed absolute system is maintained. For a line-down swap, the encoder type matches the J4 drive's native feedback interface — no adapter or converter board between the motor and the servo amplifier. The acceleration ratings tell you what the mechanical build can handle: X-axis 24.5 m/s², Y-axis 49 m/s². The Y-axis figure is roughly 5 g, so this motor can drive a vertical axis or a fast pick-and-place Z motion without oversizing the frame. The recommended load inertia moment ratio of 15 times or less is the practical tuning boundary — stay inside that and the J4 auto-tuning will converge without oscillation.
Integration notes for the panel builder
The standard build ships without an oil seal. If the application mounts the motor with the shaft pointing down into a gearbox or a wet zone, order the HG-SR_J variant with the oil seal option — that keeps lubricant from migrating along the shaft into the encoder or winding. The vibration class is V10, which is the standard level for general industrial servo duty; no special dampening required for most conveyor, rotary table, or linear-axis builds.
