What are the key features of this servo motor?

This Siemens servo motor is known for its high efficiency of 89%, a rated speed of 6000 rpm, and a rated torque of 3 Nm. It operates optimally at 0.94 kW and has a maximum permissible speed of 9000 rpm. The motor is cooled naturally and comes with a resolver for position feedback.

Can this motor be used in compact spaces?

Yes, the motor is designed with a compact form factor, making it suitable for applications where space is limited. Its mechanical data indicates a shaft height of 48, which contributes to its compactness.

What type of cooling does the motor utilise?

The motor uses natural cooling, which means it relies on the natural convection of air to dissipate heat. This is a common and efficient method for maintaining the motor's temperature within operational limits without the need for additional cooling systems.

What is the degree of protection for this motor?

The motor has a degree of protection rated at IP64, which means it is protected against dust ingress and splashing water, making it suitable for various industrial environments.

What kind of feedback system does the motor have?

The motor is equipped with a resolver, specifically a Resolver R14DQ, which provides 14-bit resolution for accurate position feedback. This is essential for precise control in servo applications.

Is there a holding brake option for this motor?

This particular model comes without a holding brake. However, the design allows for the integration of a holding brake if your application requires one.

What is the motor's efficiency and how does it impact performance?

With an efficiency of 89%, this motor operates with less power loss compared to less efficient motors. This high efficiency leads to better performance, reduced energy consumption, and potentially lower operational costs.

What are the electrical characteristics of the motor?

The motor has a winding resistance of 1.15 Ω at 20º C, a voltage constant of 44.5 V/1000*min¯¹, and an electrical time constant of 2.15 ms. These characteristics are important for understanding the motor's performance in electrical terms and for integration with compatible drive systems.

How does the motor's moment of inertia affect its operation?

The motor has a moment of inertia of 2.900 kgcm², which influences the motor's acceleration and deceleration capabilities. A lower moment of inertia allows for quicker changes in speed, which is beneficial for dynamic applications.

What applications is this motor typically used for?

This Siemens servo motor is suitable for a wide range of applications, including automation systems, CNC machinery, packaging machines, and other precision motion control tasks where high speed, torque, and accurate positioning are required.
