7 kW Power Rating Smooth Shaft (No Key) HTL 2048 Incremental Encoder IM B35 Mounting Fan Cooling IP55 Motor Protection

The Siemens 1PH7105-2JF03-0BJ3 is a SIMOTICS M compact asynchronous motor with a 7 kW power rating, operating at 1500 rpm and delivering 44.6 Nm of torque. It also provides a continuous operation (VC) rating of 8 kW at 1750 rpm and 43.7 Nm. This motor is powered by 400V 3AC 50Hz, includes fan cooling, and features a relative motor encoder (HTL 2048 incr./rev). Designed with IM B35 (IM V15, IM V36) construction, vibration severity grade R, and shaft/flange accuracy R, it offers IP55 motor protection and IP54 fan protection with a standard RAL 7016 paint finish. A key distinguishing feature is its smooth shaft without a fitted key.

This motor is ideal for applications where a smooth shaft is preferred or required for direct coupling or specific drive mechanisms. The high-resolution 2048 incr./rev encoder ensures precise control, making it suitable for advanced automation tasks.
