Aug 27 2013 2 i think its. I believe i need to wire u1 v1 w1 to power and leave u2 v2 w2 disconnected. There are 6 wires. Since you have to choose between the speeds using a two speed motor switch its impossible for both coils to become energized simultaneously. I am trying to wire up a two speed 6 wire 3 phase motor to run at its highest speed. However the wiring to the motor is the same.
Two speeds one direction three phase. Since a two speed motor relies on different coils to produce different speeds there are usually two input wires. I am trying to wire up a two speed 6 wire 3 phase motor to run at its highest speed. Below is the motor data plate and whats left of the wiring diagram. When the stop button is pressed contact td 1 waits for the specified amount of time before returning to its normally closed state thus holding the reverse pushbutton circuit open for the duration so m 2 can. And the main voltage is 480 v.
A three wire three phase circuit is usually more economical than an equivalent two wire. 2 green blue 1 low speed 2 mid speed 3 high speed green brown diagram ic1 3ø wiring diagrams 1ø wiring diagrams diagram er9 m 3 1 5 9 3 7 11 low speed high speed u1 v1 w1 w2 u2 v2 tk tk thermal overloads two speed stardelta motor switch m 3 0 10v 20v 415v ac 4 20ma outp uts diagram ic2 m 1 240v ac 0 10v outp ut diagram ic3 m 1 0. In many instances the low and high speed coils share an external wire. Power and control circuit for 3 phase two speed motor. Wiring diagram for two speed moto explained. Please let me know if im right or wrong.
The motor uses a start and run capacitor. Two separate windings designed to rotate the motor at two different speeds or inbuilt resistors which alter the voltage supplied to windings. The electric motor is a bm 122 decomin brand 3 speed motor. This being the case the normally closed timed closed contact of td 1 between wires 8 and 5 will have immediately opened the moment td 1 was energized. Two speeds two directions multispeed 3 phase motor power control diagrams. Joined aug 5 2011 messages 1567.
Multi speed 3 phase motor 3 speeds 1 direction power control diagrams. Additionally the low speed coil is typically supplied by a red wire while the high speed coil is fed by a black wire. Kindly email me the diagrams for star deltor and direct online for a 3speed 1directon 3ph motor have two of them in a bow cutter. Something was wrong with the solid state circuitry everything worked but the motor but a quick test of the motor indicated it does work. One contactor burnt for high speed and a replced contactor does not engange originally the coils re fed with a nutural and the one i replaced is only working with a phase. Read about motor control circuits ladder logic in our free electronics textbook network sites.
It has four terminals. This special motors have 6 wires and depending of the connection could run at high or low speed at only one voltage in your case the high speed is 3550 and the low is 1770 rpm. The above name plate belongs to one single windingtwo speed motor. I decided to change controls to a simple. Also for programming the vfd the highest speed setting would mean using 2 pole 43 amps and 1720 rpm. This fan has an oscillating grill with independent sync motor and timer circuit.
