Baldor Electric Company 601A100-2 DC Tachometer

The Baldor Electric 601A100-2 DC tachometer is a tachometer/generator that provides a voltage proportional to motor speed for speed feedback in Baldor DC motor systems. With an armature voltage of 50 V and a base speed of 1,000 RPM, it produces about 50 V at 1,000 RPM, i.e., 50 V per 1,000 RPM of shaft speed. The unit is commonly paired with Baldor Reliance DC motors and compatible drives to enable closed-loop velocity control. The part number is 601A100-2 (some catalogs reference the P601A100-2 designation). Catalog listings and third-party suppliers frequently quote a speed range up to 5,000 RPM, indicating suitability for moderate-speed applications. This tachometer/generator is designed specifically to provide a tach feedback signal for DC motor control and speed monitoring, helping ensure accurate speed regulation in automation setups.
