Single Phase Motor Wiring Diagram With Capacitor Start

Save

This document Crun provides essential information on Permanent Capacitor Motors and Capacitor Start Capacitor Run Motors. It covers the importance of correct wiring in preventing damage to motor capacitors and windings due to frequent stop/starts or changes in rotation direction. The document emphasizes the need for qualified electricians to reconnect terminations and highlights the usage of three-phase motors with single-phase frequency inverters for optimal performance. Additionally, it includes wiring diagrams for single-phase motors with mechanical centrifugal switches and electronic current circuits. Van Houcke UK Ltd’s contact details are also provided for further assistance. Visit their website for more details.

When a change of direction of rotation is required and a change-over switch is to be used it will be necessary to reconnect the termination on the terminal block. The reconnection must be carried out by qualified electrician.

Frequent stop/starts and/or changing of the direction of rotation will damage the motor's capacitor's and winding.

Three-phase motors with single-phase frequency inverter should be used for frequent on/off switching.

MEZ cannot be held responsible for a damage caused by incorrect wiring !!
