Types of 200mm motor shafts
A motor shaft transfers the rotating power produced by the motor to connect the component that needs to be rotated. A common illustration is the rotor inside the motor that empowers the washing machine's spin cycle. The 200mm motor shaft is relatively long and can be used to distribute torque over a greater distance, connect larger components, or situate the motor in a specific orientation.
Motor shafts can be made from a variety of materials:
- Steel motor shafts: Typically used for heavy-duty machinery, stainless steel motor shafts are generally more expensive because they offer greater resilience, corrosion resistance, and ability to undertake high-stress loads.
- Aluminum motor shafts: When weight is a priority, aluminum motor shafts are a good choice as they offer a lightweight option without compromising functionality. However, they can only perform under moderate loads.
- Plastic motor shafts: Plastic is not a very common material used in motor shafts because it can only take low loads and has little capacity for stress.
There are various shapes of motor shaft to connect with other components:
- C motor shaft: Named after the letter 'C,' this type of motor shaft is a curved shaft that extends outward from the motor in a C-like shape. The design allows easy installation and assembly into the housing space.
- Keyed motor shaft: A machined groove is created in a keyed motor shaft that runs along its length. It is then shaped to fit the groove, allowing the motor to turn or rotate various components or objects.
- Flexible motor shaft: A motor shaft that can bend and flex is known as a flexible motor shaft. It can also withstand heavy loads and connect to other machinery with ease.
- Hex motor shaft: Hex motor shafts are usually fixed motor shafts. They have a hexagonal shape and are used frequently in the brushless motor application field.
Gear shafts
A gear shaft is a type of motor shaft with a gear attached to it. The gear helps to transfer power and torque from the shaft to an object. Some gear shafts have additional features, such as splines, threads, or keyways. Noticeable differences in gear shafts include tapered shafts that narrow towards the end, drive shafts that transfer the engine's power to the wheels, counter shafts that sit parallel to the main transmission, and output shafts connected to the transmission.
Motor shaft specification and maintenance
Specification
- Length: The length of the motor shaft affects the overall size and weight of the motor. Longer shafts can accommodate larger loads but may create more inertia.
- Diameter: The diameter is the width across the shaft. A thicker shaft can support heavier loads but may be heavier and cost more.
- Keyway: The keyway is a small slot cut along the shaft. The keyway helps to lock the shaft onto other parts so they turn together. Not all shafts have keyways.
- Material: Motor shafts are usually made of steel, which is strong and sturdy. Some shafts may bemade from aluminum, which is lighter but still durable enough for certain jobs.
- Coating: Many motor shafts have a coating, like paint or chrome, to protect against rust. Rust can weaken the metal over time. The coating also helps the shaft slide into other pieces more easily.
Maintenance
- Regular inspection: Check the motor shaft periodically for any signs of wear, damage, or misalignment. Look for things like unusual noise, vibration, heating, or shaking.
- Lubrication: Apply lubricant to moving parts regularly. Lubricant reduces friction and prevents damage from overheating. Be sure to use the right amount and type of lubricant for the motor.
- Cleanliness: Always keep the motor shaft and its surroundings clean. Dirt, dust, and other materials can accumulate and cause blockages, leading to malfunctions. Wipe away any debris and do a thorough cleaning when needed.
- Repair wear promptly: If you notice any unusual wear, get repairs done quickly. Allowing minor scratches or damage to remain can lead to more significant problems over time. Fixing small issues promptly can prevent expensive repairs down the road.

How to Choose 200mm motor shafts
Buying shafts entails more than just referring to a catalogue. One must know what type of motor shaft will work best for the business client's needs, including quality and compatibility. To start, clients need to determine the size of the shaft they want to purchase. The key dimensions to note for compatibility with the motor and gear casing are the outer diameter, inner diameter, and length. The motor must properly fit the gear where it will be installed. Clients must also ensure that the gear is made to support the weight and length of the incoming shaft.
The next step is to select the type of material used to construct the gear. Clients must have a clear idea of what their final application entails. If the application requires resistance to extreme temperatures or corrosive environments, they will need to get stainless steel shafts, PVC shafts, or shafts made out of any other rust-resistant material.
Brittleness is another factor that buyers need to consider. Motor shafts need to bend slightly to avoid breaking, so they should be made from flexible materials. Clients can get shafts made from carbon steel or any other flexible material. Clients should also pay attention to the coupling method. Ensure that the gear being purchased has a coupling method that works for the client's appliance or machine. Most motor shafts feature the following coupling methods: flanged, splined, or keyed.”
Lastly, buyers must ensure that the gear has been tested as per ISO standards.
