HG-SR152J is a 1.5 kW AC servo motor from Mitsubishi's HG-SR series, rated for 2000 r/min continuous speed with a 9.4 A current draw at full load. Maximum torque hits 21.5 N·m — enough for a decent acceleration reserve on indexing applications. The J suffix means it ships with an oil seal, so it can handle a bit of splash in a gearbox environment without weeping grease into the encoder.
Environment & Mounting Fit
The motor is rated for indoor installation away from direct sunlight, corrosive gas, oil mist (outside the seal), dust, and dirt. Vibration rank V10 means it's built for the usual rotating machinery shake, not a high-vibration press. Insulation class 155 (F) gives thermal headroom up to 155 °C winding temperature; paired with the oil seal, it'll survive a cabinet sharing space with a gear reducer as long as the ambient stays within standard industrial limits.
