Baldor Electric Company M1729T Two Speed AC Motor

Baldor Electric Company M1729T is a rugged dual-speed AC motor designed for industrial equipment requiring two fixed operating speeds. It provides 25 HP at the high-speed setting and 11 HP at the low-speed setting, with shaft speeds of 1800 RPM on the 4-pole high-speed setting and 1200 RPM on the 6-pole low-speed setting at 60 Hz. The motor is configured for 460 V three-phase service and is housed in a TEFC (Totally Enclosed Fan Cooled) enclosure to protect windings from dust, moisture, and typical shop-floor contaminants. It uses a 324T frame and is foot-mounted for straightforward installation and replacement in standard Baldor-Reliance installations. Rated for continuous-duty operation, the M1729T is suited to machinery that benefits from two defined speed ranges—such as material handling, fans, or pumps—without requiring frequent speed-changing equipment. This Baldor-Reliance model integrates with common spare parts and service channels, making it a practical choice for retrofit projects or new installations that demand reliable dual-speed operation at 60 Hz and 460 V.
