Mitsubishi Electric HC153T-SZ AC Servo Motors

The Mitsubishi Electric HC153T-SZ is a brushless, 3‑phase AC servo motor from the HC Series designed for precision motion control in CNC machines and industrial automation systems. It delivers about 1.5 kW of rated output at roughly 3000 RPM, with 120–131 VAC 3‑phase input and a rated current around 8–9 A. The motor uses encoder feedback via a pulse encoder (model-dependent, often OSE series) and is offered with keyed or tapered shaft variants for flange‑mount installation. Weighing about 20 lb (9 kg) and configured for flange mounting, it suits machine tools, robotic systems, conveyor positioning, packaging machinery, and automated assembly where precise speed, torque, and repeatability are critical. As a discontinued/legacy model, common replacements include Mitsubishi HC-RP153 and HC-RFS153K.
