Product description

The Siemens SIMOTICS M compact asynchronous motor, part number 1PH7133-2EG33-0BJ3, is designed for applications demanding high speed and precise control. It delivers 20 kW at 2000 rpm with a torque of 95.5 Nm, and can reach 22.5 kW at 2300 rpm. Operating on 400V 3AC, 50 Hz, this motor includes integrated fan cooling (IP55 motor, IP54 fan) and an absolute motor encoder (1 VSS 2048 P/U) for accurate position feedback. A distinctive feature of this model is its smooth shaft without a fitted key, designed for specific coupling methods. The motor is built with IM B35 construction.

This motor is particularly suitable for applications that utilize specific shaft coupling mechanisms, such as direct shaft mounting with specialized collars or friction couplings, common in high-speed machinery, dynamometers, or certain types of industrial pumps. Its high speed and precise encoder feedback make it valuable for dynamic performance requirements.

Frequently asked questions

What are the implications of a 'smooth shaft without fitted key' on the 1PH7133-2EG33-0BJ3 motor?

A smooth shaft without a fitted key on the Siemens 1PH7133-2EG33-0BJ3 motor means it relies on alternative methods for torque transmission, such as clamping hubs, friction couplings, or direct mounting. This design is often chosen for high-speed applications or where precise concentricity is critical.
