Single phase motors are designed for either CW or CCW operation, 3 phase units can be set by swapping any 2 power input connections. Manufacturer: Delta Model: 62-045 Voltage: 120/240 H.P. : 1 1/2 Dual capacitor (Start/Run) ---------------------------------------------------------------------------------------------------------------
Need to change rotation on this motor. I believe that if I changed the polarity on the Start circuit that I could do this ?? I do not know how to go about this, therefore could you please help me out here.
With Warm Regards,
Marco

How do you change rotation on a Century AC motor?
There are two alternate methods depending on whether the motor is single phase or three phase. On a single phase motor, reverse either the start winding coil lead or the run winding coil lead but not both. This action will reverse the motor's rotation. On a three phase motor, interchanging any two of the three coil leads will reverse the motor's rotation.
How can rotation be change of single phase motor?
With the starting winding disconneted the motor will start up in whichever direction it is spun. To make the starting winding operate the other way, it needs an inductor in series insead of a capacitor. Details depend on the motor, but the reactance of the inductor should match that of the capacitor.
When changing phase rotation of a 3 phase motor is this done at the switchboard?
The phase rotation of motor should be always done from motor side i.e The motor terminal box.
How do you change rotation on a single phase motor crompton parkinson class e?
You need to reverse the polarity of starting winding. You need to open the terminals. Get expert help.
You have one hp three phase motor where as available power supply is only single phase how can you run this motor?
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
How do you change the direction of 3 phase motor?
Reverse any two line leads connected to the motor will reverse the directional rotation of the motor
What equipment is used to check phase rotation?
A phase rotation meter. Or a small three phase motor can be wired up and its rotation observed.
How is direction of rotation for single phase induction motor determined?
A single phase induction motor is not self starting; thus, it is necessary to provide a starting circuit and associated start windings to give the initial rotation in a single phase induction motor. The normal running windings within such a motor can cause the rotor to turn in either direction, so the starting circuit determines the operating direction.
What is the type of switch that reverses the rotation of a single phase motor?
If you are talking about a switch that is used to change the direction that a single phase motor turns from clockwise to counter clockwise, the switch is called a forward - reverse drum switch. By reversing any two of the three phase legs that feed the 3 phase motor. <<>> On a single phase motor a drum switch is used. This switch reverses the start winding so that when voltage is applied to the motor it will revolve in the reverse direction.
Can you replace a 480-240V 3-phase motor with a single phase motor as a temporary replacement or will it burn it out?
Yes, you can, and it won't burn out IF>>> the horsepower rating is the SAME. Pay attention to wiring and motor rotation. Also check the voltage: the motor voltage must be the same as the voltage between two hots of your 3 phase system. You will only use two hots as this is a single phase motor.
How do you check single phase motor winding?
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
Why do you use codenser in fan?
fan is a capacitor start capacitor run single phase induction motor. since single phase induction motors are not self starters, caused by discontinuty in stator mmf. so to iniate rotation single phase supply is splitted 90 degree apart by a capacitor to convert it to a 2 phase motor, which produces a continued synchronously revolving mmf in stator to start the motor. cool !!
