You should learn how an electric motor works before picking one for your machine. The biggest difference is that a synchronous motor keeps the same speed, but an asynchronous motor can change its speed. Electric motors make machines like construction hoists and cranes move. People use electric motors every day in building work. Choosing the right electric motor helps your hoist or crane stay safe and work well.
Synchronous motors always run at the same speed. Their speed matches the power supply frequency. This makes them great for jobs that need exact speed control.
Asynchronous motors can start by themselves. They change speed when the load changes. This makes them good for machines like hoists and cranes.
Pick a synchronous motor if you need steady speed. Use an asynchronous motor for heavy lifting and changing loads.
Think about efficiency and price. Synchronous motors can save more energy but usually cost more. Asynchronous motors are cheaper and easier to fix.
For building projects, use Nantong Haibao's asynchronous motors. They work well, start easily, and are safe.

You might wonder, how do synchronous motors work? A synchronous motor runs at a constant speed. The speed matches the frequency of the electric power supply. When you turn on a synchronous motor, the rotor locks in with the rotating magnetic field. This means the rotor and the magnetic field spin together at the same speed. You will not see any difference between the speed of the rotor and the speed of the magnetic field. This is why people call it a synchronous motor. The motor does not slow down or speed up under normal loads. Synchronous motors keep their speed steady, even if the load changes.
You can spot some key characteristics of synchronous motors right away. Here are the key characteristics you should know:
Synchronous motors always run at a fixed speed.
The speed depends on the frequency of the power supply, not on the load.
Synchronous motors need extra help to start. They often use special devices to get up to speed.
These motors do not have slip. The rotor and the magnetic field move together.
Synchronous motors can improve the power factor in electrical systems.
These key characteristics make synchronous motors different from other types of motors. You will find that the key characteristics of synchronous motors help in jobs where you need steady and reliable speed.
You will see synchronous motors in places where you need exact speed control. Many factories use synchronous motors for machines that must run at the same speed all the time. You might find them in clocks, timers, and some types of pumps. Synchronous motors work well in precision equipment. In construction, you usually need motors that can handle changing loads and start easily. For hoists and cranes, you often choose other types of motors. Synchronous motors are not as common in construction hoists and cranes because these machines need motors that can start under heavy loads and adjust speed if needed. Still, you should know about synchronous motors so you can pick the right motor for your project.
You might wonder how asynchronous motors work. These motors have a simple but smart design. The stator makes a magnetic field that spins the rotor. The rotor does not spin as fast as the magnetic field. This speed difference is called slip. Slip helps the asynchronous motor make torque and start on its own. You do not need extra devices to start it. This makes asynchronous motors very popular in many machines.
There are many important things about an asynchronous motor. Here are some main points:
Asynchronous motors have a simple and strong build.
These motors can start by themselves without special tools.
The speed changes a little when the load changes.
Slip helps the motor make power and handle heavy loads.
Asynchronous motors need less care than other types.
Asynchronous motors are reliable and easy to use for many jobs. Their design makes them great for machines that start and stop a lot.
You will find asynchronous motors in many construction machines. Construction hoists and cranes need motors that can lift heavy loads and start smoothly. Nantong Haibao uses advanced asynchronous motor technology in its hoists and cranes. The electromagnetic braking asynchronous motor, like the YZE132 and YZEP132, gives safe and smooth operation. These motors give strong power and quick braking, which is important for lifting and lowering things. You can trust asynchronous motors to work well in tough construction places. The strong build and self-starting feature make the asynchronous motor the best choice for your hoist or crane. When you pick Nantong Haibao’s asynchronous motors, you get good performance, safety, and long life for your projects.
When you pick an electric motor for your construction machine, you need to think about a few important things. You might wonder how a synchronous motor and an asynchronous motor are different. This part will show you each point so you can choose the best one for your job.
Speed is a big way these motors are not the same. A synchronous motor always keeps the same speed. The speed matches the power supply’s frequency. The rotor in a synchronous motor turns at the same speed as the magnetic field. There is no slip at all. The speed stays the same, even if the load gets heavier.
An asynchronous motor works in another way. The rotor in an asynchronous motor turns a little slower than the magnetic field. This small difference is called slip. Slip helps the asynchronous motor make torque and start by itself. The speed of an asynchronous motor can change a bit when the load changes. This is good for hoists and cranes because the weight can be heavy or light.
Here is a simple table to help you see the difference:
Point of Comparison | Synchronous Motor | Asynchronous Motor |
|---|---|---|
Speed | Constant | Changes with load |
Slip | None | Present |
You should know how each motor starts. A synchronous motor cannot start by itself. It needs a special device or another motor to get up to speed. When it reaches the right speed, the synchronous motor locks in with the magnetic field and runs smoothly.
An asynchronous motor can start on its own. You do not need extra devices. You just turn on the power and the asynchronous motor starts spinning. This makes the asynchronous motor easy to use in many machines.
Tip: For hoists and cranes, you want a motor that starts easily and lifts heavy loads. Nantong Haibao’s electromagnetic braking asynchronous motor gives you smooth starting and safe stopping every time.
You should think about how well the motor works and how much it costs. A synchronous motor can be very efficient, especially if you need steady speed. It can also help your electrical system work better. Sometimes, a synchronous motor costs more because it needs extra parts to start.
An asynchronous motor is usually cheaper. It has a simple design and does not need special starting devices. The asynchronous motor works well in many places and needs less care. You will see that the cost to buy and use an asynchronous motor is often lower.
Here is a quick look:
Synchronous motor: High efficiency, higher cost, steady speed.
Asynchronous motor: Good efficiency, lower cost, easy to use.
You want to use the right motor for your job. A synchronous motor is best when you need exact speed control. You might use it in machines that must run at the same speed all the time. You will not see synchronous motors much in hoists or cranes.
An asynchronous motor is great for construction machines. You can use it in hoists, cranes, and elevators. Nantong Haibao uses strong asynchronous motors, like the YZE132 and YZEP132, in their hoists. These motors give you strong lifting power, smooth running, and safe braking. The electromagnetic braking system helps you stop and hold loads safely. You can trust these motors to work well in tough places.
Note: If you need a motor for a hoist or crane, pick an asynchronous motor from Nantong Haibao. You get good performance, easy starting, and long life for your equipment.
Both the synchronous motor and the asynchronous motor have their own good points. You should look at what your project needs and pick the motor that fits best.
