Siemens Three-Phase Squirrel Cage Motor 1LE1501-1EA23-4AA4-Z — BOLTON SKU 53619.
About the Siemens Three-Phase Squirrel Cage Motor
This Siemens Three-Phase Squirrel technical component is a two-pole squirrel-cage induction motor built to order code 1LE1501-1EA23-4AA4 in frame size 180M. It is rated 22 kW on a 50 Hz supply and 24.5 kW on 60 Hz. The 50 Hz winding is configured for 3 AC 400 V in delta or 690 V in star, and the 60 Hz rating applies at 3 AC 460 V in delta, so the same machine can be commissioned on either supply frequency by selecting the correct connection. Construction is IM B3 — foot-mounted with a horizontal shaft — with the terminal box positioned at the top of the frame. The motor is supplied without integral motor protection, so overload and thermal protection must be provided in the starter or drive. Unless a different colour is specified by order code, the standard paint finish is RAL 7030.

Typical applications
A two-pole 22 kW machine runs at high synchronous speed, which is why this configuration is normally selected for pumps, fans, blowers and compressors rather than low-speed, high-torque drives. Foot mounting in the B3 arrangement suits baseplate and skid installations where the motor is coupled directly or through a belt drive. Because protection is not integral, this motor is intended for installations where a starter, contactor or variable-speed drive already provides overload and thermal monitoring.
