Frequently Asked Questions
What are the installation benefits of using a plain shaft with a shaft seal?
A plain shaft simplifies coupling with external mechanical components while the seal prevents fluid ingress. This design ensures reliable operation in dusty or high-moisture environments.
Can the MHD112B-035-NG0-AN operate effectively without a holding brake?
Yes, but the absence of a holding brake requires external mechanical locking when stationary loads must be maintained. It’s ideal for systems with separate load-holding mechanisms or horizontal motion axes.
How does relative position detection affect homing and startup procedures?
Since the encoder detects position relatively, a reference or homing cycle is needed after power-up. This ensures consistent coordinate mapping for automated motion sequences.
How does continuous torque at standstill influence servo tuning and load response?
The 28 Nm torque capability allows stable holding force during static loads without overheating. It supports precise tension control and consistent output in holding applications.
In what applications is the MHD112B-035-NG0-AN typically integrated?
This motor is often used in CNC machining centers, printing lines, and packaging automation. Its liquid cooling and encoder precision make it suitable for continuous, high-accuracy motion control systems.
