Can this motor be used in precision applications?

Yes, this motor is designed for precision applications, featuring an absolute encoder with high resolution for accurate positioning and control.

What type of cooling method is used in this motor?

This motor utilises natural cooling, which means it relies on the natural convection of air to dissipate heat without the need for additional cooling mechanisms.

What is the degree of protection for this motor?

The motor has a degree of protection rated at IP64, which indicates a good level of protection against dust ingress and splashing water.

What is the significance of the motor's moment of inertia?

The moment of inertia is a measure of the motor's resistance to changes in rotational speed. A lower value typically means the motor can accelerate and decelerate more quickly, which is beneficial for dynamic applications.

Does this motor come with a holding brake?

No, this model does not include a holding brake. It is equipped with a plain shaft and is designed for applications where a holding brake is not required.

What type of encoder does the motor use?

The motor is equipped with an Encoder AM22DQ, which is an absolute encoder with a resolution of 22 bits and a multi-turn range of 4096 revolutions.

What are the mechanical data specifications for this motor?

The mechanical data specifications include a radial runout tolerance of 0.040 mm, an axial runout tolerance of 0.08 mm, and a shaft torsional stiffness of 16000 Nm/rad.

How is the temperature within the motor monitored?

Temperature monitoring is achieved through a KTY84 temperature sensor located in the stator winding, ensuring the motor operates within safe temperature ranges.

What applications is this motor typically used for?

This motor is typically used in applications requiring high precision and dynamic performance, such as CNC machinery, robotics, packaging machines, and other automation systems.
