Industrial-grade 120V rheostat motor speed controllers engineered for precise automation of analog devices. Available in 25W, 50W, and 100W configurations with 115 VAC reversible motors, offering RPM ranges from 1-15 for reliable process control applications.






Controlling the speed of a 120V AC motor in industrial applications requires a compatible speed controller, such as the 120V rheostat motor speed controllers featured here. These units use variable resistance technology with 115 VAC reversible motors to deliver precise speed control in the 1-15 RPM range. Available in 25W, 50W, and 100W configurations, they allow operators to fine-tune motor speed for automation and process control tasks. For seamless integration into automated environments, select models also accept 0-10 volt inputs for PLC connectivity. It is important to note that standard AC induction motors are not compatible with rheostat-based control — always verify motor compatibility with a technical specialist before selecting a controller.
