Frequently Asked Questions
What are the key specifications of this synchronous servo motor?
This Siemens synchronous servo motor is designed for high performance with a rated power of 1.02 kW, a rated current of 3.1 A, and a maximum speed of 6000 rpm. It has a rated torque of 3.0 Nm and features natural cooling, a plain shaft, and an absolute encoder with EnDat interface.
Can this motor be used in a position control application?
Yes, the motor is equipped with an absolute encoder that provides precise position feedback, making it suitable for applications requiring accurate position control.
What type of cooling does the motor use?
The motor utilises natural cooling, which means it relies on the natural convection of air to dissipate heat without the need for additional cooling mechanisms.
Is there a holding brake option for this motor?
Yes, the motor comes with an optional holding brake that can secure the motor in position when power is not applied, enhancing safety and control in certain applications.
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 type of encoder system does the motor have?
The motor is equipped with an Encoder AM2048S/R, which is an absolute encoder with 2048 single-turn resolution and 4096 revolutions multi-turn capability, featuring an EnDat interface for high-resolution feedback.
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, which affects the dynamic response of the motor. A lower moment of inertia allows for quicker acceleration and deceleration, which is beneficial in dynamic applications.
How does the thermal time constant affect motor performance?
The thermal time constant indicates how quickly the motor reaches thermal equilibrium under load. A longer thermal time constant means the motor can run longer before reaching its maximum operating temperature, affecting duty cycle and performance.
What applications are suitable for this motor?
This motor is well-suited for a variety of applications including automation, CNC machinery, robotics, and any system requiring precise motion control and high-speed operation.
