Speed Control US-52 90W

Description

Product Description: US-52 90W AC Motor Speed Pinpoint Regulator The US-52 (90W variant) is a panel-mountable, electronic speed governor used to precisely adjust the rotational speed of single-phase AC motors. Operating on a standard 220V–240V AC (50Hz/60Hz) supply, it utilizes a front-facing rotary potentiometer knob calibrated from 0 to 100% (or specific RPM scales) alongside an integrated rocker ON/OFF switch. Unlike a simple dimmer, the US-52 relies on a feedback circuit connected to a motor’s internal tachogenerator (speed sensor). This allows it to dynamically adjust power to maintain stable speed and torque even when the mechanical load changes. Key Technical Features Power Rating: Rated for AC motors up to 90 Watts (ensure the motor wattage does not exceed this rating to prevent overheating the controller). Speed Range: Typically controls speeds from 90 RPM up to 1400 RPM or 1700 RPM (depending on grid frequency). Directional Control: Supports both Forward (CW) and Reverse (CCW) wiring configurations via the terminal block on the back. Connector Interface: Usually equipped with a standard 6-pin/5-pin square plug layout for quick plug-and-play installation with matching motor blocks. Compatible Mechanisms & Machinery The US-52 controller is specifically designed for micro-reduction AC gear motors that feature a built-in tachometer feedback coil. It will not work properly on standard heavy-duty induction motors without speed feedback or on DC brushless motors. It is highly compatible with the following hardware and mechanisms: 1. 90W Single-Phase AC Speed Control Motors Compatible Hardware: Brands like T.W.T, Oriental Motor, Panasonic, and generic 90W AC gear motors with a 5-wire or 6-wire lead output. Application: The motor must have two wires for the main power, two wires for the internal capacitor, and two wires for the tachogenerator feedback coil which plugs directly into the back of the US-52. 2. Packaging & Conveyor Line Mechanisms Compatible Mechanisms: Small assembly line conveyor belts, heat-shrinking packaging tunnels, and bottle capping machinery. Application: Operators turn the dial on the US-52 to speed up or slow down a conveyor belt to match the manual assembly pace of workers or the processing time of a packaging machine. 3. Printing & Labeling Equipment Compatible Mechanisms: Automated labeling rollers, paper feed rollers, and commercial printing press auxiliary winders. Application: Controls the tension and speed of paper or labels feeding through a machine to prevent tearing or wrinkling. 4. Food Processing & Mixing Machinery Compatible Mechanisms: Small dough kneaders, liquid mixers, spice grinders, and commercial rotisseries. Application: Allows chefs or factory operators to slow down a mixing paddle for heavy ingredients or speed it up for lighter blending. 5. Lab & DIY Automation Gear Compatible Mechanisms: Winding machines (for copper coils), laboratory stirrers, and specialized rotary tables. Application: Provides cheap, reliable, and smooth stepless velocity adjustments for custom-built small shop mechanisms.
