Read here to know about the shaded pole motors their constructional features working and how they are used in starting of single phase induction motors. The stator poles are equipped with an additional winding in each corner called a shade winding as shown in fig4.

Shaded pole motor wiring diagram. As there is time and space displacement between the two fluxes the rotating magnetic field induces in the coil. A shaded pole motor may be of 2 poles or 4 poles. Connect the ecm motor speed control signal negative wht wire and positive blk wire leads to the supplied or any 18awg wire and connect to the control negative and positive pwm or vdc terminals per wiring diagram on page 7. And manufacturers wiring schematics also use diagrams b and c to ensure a positive troubleshoot ing application. In this motor small single turn copper shading coils create the moving magnetic field.

Shaded pole motor wiring diagram the shaded pole motor is the original type of ac single phase induction motor dating back to at least as early as a shaded pole motor is a small. Working of shaded pole induction motor. The various applications of the shaded poles motor are as follows they are suitable for small devices like relays and. The field rotates from the unshaded portion to the shaded portion of the motor. A common single phase motor is the shaded pole motor which is used in devices requiring lower torque such as electric fans microwave ovens and other small household appliances. The pole structure of the shaded pole motor enables the development of a rotating magnetic field by delaying the buildup of magnetic flux.
Construction of shaded pole induction motor. Some single phase induction motors are also called squirrel cage motors because of the rotors similarity to. A shaded pole motor includes a winding which is placed around the pole part that holds up the magnetic field phase. Here we are considering a 2 pole shaded pole motor. Mount the ecm motor with the wire harness in the down position. Applications of the shaded pole induction motor.
Reserves the right to change any specifications or data without notice. Refer back to this diagram as the operational requirements of the single phase motor are discussed. The single phase induction motor is much the same in construction as the three phase motor. In the salient pole configuration machine the magnetic field pole can be generated produced with a winding wound approximately under the pole face. A copper conductor isolates the shaded portion of the pole. The rotating magnetic field develops the starting torque in the motor.
Figure 17 3 shows a very basic one line diagram of the single phase motor. Shaded pole motor wiring diagram. In the non salient pole configuration the winding can be dispersed within slots of pole face. Some kinds of motors include conductors with thicker metal like sheets of metal otherwise bars generally copper otherwise aluminum. These windings have no electrical connection for starting but uses induced current to make a rotating magnetic field. Part of each pole is encircled by a copper coil or strap.
Construction of shaded pole induction motor. The figures in this article also show a 2 pole motor. Construction of shaded pole induction motor. A shaded pole motor and its schematic diagram are shown in the figures above. Shaded pole motor is one of the types of single phase induction motors which are used for producing a rotating stator flux in order to make the single phase induction motor a self starting onelet us discuss the constructional details diagrams and working of shaded pole motors in detail. The connection diagram of the shaded pole motor is shown below.
Characteristics of shaded pole motors. Ensure that pwm type motors are connected to the control pwm terminal blocks and vdc motors to the vdc. The induced current in the strap opposes the change of flux through the coil lenzs law so that the maximum field intensity moves across the pole face on each cycle. Bracket from the evaporator to replace the shaded pole motor with the new ecm motor.
