CSR Motor

รูปภาพ
CSR Motor Definition and Characteristics CSR means Capacitor Start Capacitor Run (CSCR), typically shortened to CSR High starting torque Can handle high-demand loads 1-10 HP Can be designed for lower full-load currents and higher efficiency Operates at lower temperature than other single-phase motor types of comparable horsepower Only disadvantage to a CSR motor is its higher price - mostly the result of more capacitors, plus a starting switch Able to handle applications too demanding for any other kind of single-phase motor A CSR motor uses a potential relay or start relay (see Discussion below) Discussion Potential or "voltage" starting relays are used with single-phase capacitor-start/capacitor-run motors, which need relatively high starting torque. Their main function is to assist in starting the motor. These starting relays consist of a high-resistance coil and a set of normally closed contacts. The coil is wired between terminals 2 and 5, with the con...

Electrical Wiring Diagram Star Delta Control and Power Circuit Using Mitsubishi PLC Program

รูปภาพ
This article is intended to diagrammatically demonstrate the concept of the wiring principle of a star delta (wye delta) motor control and power circuit when using a PLC (Programmable Logic Controller) ladder program to control the switching of a 440 volts induction motor. The electrical components comprising the hardware parts of the circuit includes: 1.) 440 volts to 220 volts step-down transformer - 1 piece 2.) 220 volts to 24 volts step-down transformer - 1 piece 3.) 24VAC to 24VDC power supply converter - 1 piece 4.) Normally-open push  button  switch -  2 pieces 5.) Mitsubishi PLC (Programmable Logic Controller) Type FX2N-16MR-ES - 1 unit 6.)  Auxiliary  relay with 24VDC coil and minimum 1 Normally-open contact - 3 pieces 7.) 3 phase 440 volts AC NFB (No-fuse Breaker) circuit breaker (ampere rating depends on motor capacity) - 1 piece 8.) 3 phase 440 volts AC magnectic contactor with 220 VAC coil (ampere rating depends on motor capaci...
