2. Motor selection is a big question. If you choose the right one, the performance and price of the motor will be reasonable. If you choose the wrong one, you will spend money on something that is not what you want. Therefore, we have compared the three main categories of motors in a simple way for everyone. Capacity is easy to understand.

AC series motor

Permanent magnet DC motor

Brushless DC motor

 2.1 Comparison of no-load motor characteristics

Motor type	No load
	input power	efficiency	Rotating speed	Torque
AC series motor (PU6330)	middle	middle	high	Low
Permanent magnet DC motor (PT2745)	Low	middle	middle	Low
Brushless DC motor (PBL6525)	high	Low	middle	Low

From

From the above no-load state, the speed of the AC series pole motor is relatively high. Those who have requirements for noise should pay special attention to it. Those who need to start from a low speed without load can choose a permanent magnet DC motor. In other aspects, it is not worth comparing at no load. .

2.2 Comparison of motor characteristics at maximum efficiency:

Motor type	Maximum efficiency
	input power	efficiency	Rotating speed	Torque
AC series motor (PU6330)	middle	middle	middle	middle
Permanent magnet DC motor (PT2745)	middle	middle	middle	middle
Brushless DC motor (PBL6525)	high	high	middle	high

From the above maximum efficiency point, AC series-pole motors and permanent magnet DC motors perform equally well, and their costs are similar. However, permanent magnet DC motors require an AC-to-DC rectifier in the power supply, and the cost increases slightly.

Since the permanent magnet DC motor uses a DC power supply, the effective value of the input power is larger than that of the AC series-pole motor, so it is relatively stable when used with a load and has less speed reduction than when it is loaded.

The performance of brushless DC motors is particularly powerful and is very superior at the load point, but it needs to be considered that the cost of brushed DC motors is more than 10 times higher. This is why the retail price of finished products using brushless DC motors is more than a thousand yuan.

 2.3 Comparison of motor characteristics at maximum output power

Motor type	Maximum output power
	input power	efficiency	Rotating speed	Torque
AC series motor (PU6330)	high	llow	Low	middle
Permanent magnet DC motor (PT2745)	Low	middle	high	Low
Brushless DC motor (PBL6525)	very high	high	high	high

At maximum output power, both AC series pole motors and permanent magnet DC motors are not recommended for use at this load point, while brushless DC motors still perform strongly. The only consideration is cost.

For traditional products, because price is the key point to attract users, brushless DC motors are not very versatile at present. However, through the miniaturization, speed and lightweight of brushless DC motors, the product experience has been improved.

In addition, it is easy to cooperate with electronic control to produce variable performance, and the life of the motor is no longer limited by carbon brushes, so it is often used in high-end products.
