Frequent question: Does a 4 pole motor have more torque?

What is the difference between a 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 a 4 pole motor mean?

Poles = number of poles of your motor. So, for example, if you have a 4 pole motor on 60 Hz then RPM=60*(2/4)*60=1800 rpm. 60Hz is the most common frequency in the US. 50Hz is the most common frequency outside the US.

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 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.

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.

How is motor pole count calculated?

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).

What is a 4 pole breaker?

4 Pole MCB: 4pole MCCB for 4 wires connections, the one additional 4th pole for neutral wire connection so that between neutral and any of the other three will supply. In 4-Pole MCCBs the neutral pole is also having protective release as in the phase poles. Application: Three Phase Supply with Neutral.
