What is the smallest shaded pole motor size in HP?

Shaded-pole motors are best suited to low-power household application, because the motors have low starting torque and efficiency ratings. Because of the weak starting torque, shaded-pole motors are built only in small sizes ranging from 1/20 to 1/6 hp.

What is the horsepower range of shaded pole motors?

They are built in power sizes up to about 1⁄4 horsepower (190 W) output. Above 1⁄3 horsepower (250 W), they are not common, and for larger motors, other designs offer better characteristics.

What is the highest HP for a shaded pole motor?

For extremely small capacities up to 1/40 hp (18.7W), the shaded-pole type of motor is most frequently used. It provides sufficient torque for fans, blowers, and other similar equipment, and the starting current is not objectionable on lighting lines.

What is the highest HP for a single phase motor?

Single Phase Power Solutions introduces the world’s first 100-hp single-phase electric motor. The Belle Single-Phase Motor uses Written-Pole technology to deliver a 100-hp single-phase motor that is compatible with readily-available single-phase utility services.

How do I identify a shaded pole motor?

Definition: The shaded pole induction motor is simply a self-starting single-phase induction motor whose one of the pole is shaded by the copper ring. The copper ring is also called the shaded ring. This copper ring act as a secondary winding for the motor.

Is shaded pole motor self-starting?

What is Shaded Pole Motor? Definition: A shaded pole induction motor is a simple single-phase induction motor, which is self-starting with one of the poles shaded by the copper ring. The other name of the copper ring is a shaded ring, where it acts as a secondary winding motor.

What is the efficiency of a shaded pole motor?

The efficiency of shaded pole motors generally is only between 15 and 30%. And the power factor is rather low as well. A low power factor and efficiency is probably ok for applications where there is only one small fan (shaded pole motors are generally 40 W or less).

How does a shaded pole motor start?

A Shaded Pole motor is an AC single phase induction motor. The auxiliary winding, which is composed of a copper ring, is called a shading coil. … When power is applied to the stator, the flux in the main part of the pole induces a voltage in the shading coil, which acts as a transformer secondary winding.

How many windings does a shaded pole motor have?

Unlike other types of single phase motors, shaded-pole motors have only one main winding and no start winding or switch.

How many HP is a single-phase motor?

1 HP Single Phase Motor

Speed (RPM) 1440
Voltage 180-220
Rated Power
Minimum Order Quantity 15 Piece

What is a 1 phase motor?

What is a single-phase motor? A single-phase motor is an electrically-powered rotary machine that can turn electric energy into mechanical energy. It works by using a single-phase power supply. They contain two types of wiring: hot and neutral. Their power can reach 3Kw and supply voltages vary in unison.

What is heating time constant of motor?

Heating time constant is defined as the time taken by the machine to attain 0.623 of its final steady temperature rise. The heating time constant of the machine is the index of time taken by the machine to attain its final steady temperature rise.

How does a shaded pole motor fail?

Shaded Pole motors have very low torque, so it doesn’t take much in the way of bad lube, grime, bearing friction etc. to stall them. On the plus side, they tend to last forever if you keep them clean and maintained.

What is the working principle of shaded pole motor?

The working principle of shaded pole induction motor is simple, the main winding carries alternating current and produces magnetic flux in the stator coil. The same magnetic flux cut by the copper shaded band. Due to this, the EMF will be induced in the copper band.

What are shaded pole motors most likely to be used for?

Shaded pole motors are used for low torque applications and usually rate less than 1/10 horsepower. They are often used for very small evaporator fan motors. Split Phase Motors are used for fractional horse power duty with small starting loads.
