What Does Number Of Poles Mean For Rc Motors?

What’s the difference between 4-pole and 6 pole motor?

Using this equation, a 4-pole motor at 60Hz has a speed of 1,800 rpm, while a 6-pole motor at 50Hz has a speed of 1,000 rpm. In a synchronous motor, the rotor uses a permanent magnet or electromagnet to rotate at the calculated speed. On the other hand, an induction motor will operate slightly below the calculated rpm.

What does the number of poles on a motor mean?

The pole count of a motor is the number of permanent magnetic poles, north and south, on the rotor. There is always the same number of north and south poles on the rotor. For example, in a 12 pole motor, there are 6 north poles and 6 south poles. This motor would also be considered a 6 pole-pair motor.

How many Poles does my brushless motor have?

Common in runner motors have 2 or 4 magnetic poles. There are some motors containing 6 poles as well. Outrunner motors may have in excess of 6 magnetic poles.

What is the difference between 2 pole and 4-pole brushless motor?

As the name implies, a 2-pole motor has 2 electromagnets; 1 north and 1 south. A 4-pole motor has 4 eletromagnets; 2 north and 2 south. Basically, a 2-pole motor is a good RPM motor while a 4-pole motor, having more magnets, will have more torque.

How many RPM is a 6 pole motor?

Six-pole motors run at 1200 RPM unloaded and between 1050 and 1175 RPM loaded.

How do I know what pole My motor is?

The actual running speed is the synchronous speed minus the slip speed. To determine the number of poles, you can read the data plate directly or calculate it from the RPM stated on the data plate or you can count the coils and divide by 3 (poles per phase) or by 6 (pairs of poles per phase).

Is a 2 pole motor 3 phase?

On a three-phase motor the pole pattern has to be repeated for each phase. Therefore a 2=pole, 3-phase motor will have six poles.

How many coils does a 6 pole motor have?

To create a six pole motor use six coils per phase that creates three north poles and three south poles and so on. The number of stator slots is always a multiple of six.

How does a shaded pole motor start?

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.

Why is my brushless motor cogging?

One common cause of cogging is that the startup current settings are not set appropriately. This is especially true in applications where startup occurs under load. Increasing the power going into the motor at startup can give the motor the ‘extra kick’ that it needs to avoid cogging.

What does 12N14P mean?

Another important metric describing the inner structure of a brushless motor is its motor configuration, also known as framework. For example 12N14P, where N denotes the number of stator “wire wound” poles and P denotes the number of rotor “permanent magnet” poles[ref].

What is a 8 pole motor?

If it is an 8-pole motor is will have 8 field coils evenly spaced all the way around it. Now, in an AC Motor with 3-phases you will have the 8-poles 3 times. That means you would have 24-groups of coils.

Is a 4 pole motor brushless?

Brushless motors are ideal for heavy duty servo applications with frequent overload conditions as well as for continuous duty applications where maximum operational lifetime is required.

What does 4 pole switch mean?

Four-way switches are used to control lighting from three or more locations. There are four terminals that provide two sets of toggle positions on a four-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals.

Does higher KV mean faster motor?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.
