Frequently Asked Questions
How does the MAC025A-0-WS-3-E/040-B-1/S001 ensure shaft stability during emergency stops or shutdowns?
It includes a 6.5 N·m blocking brake that locks the shaft during power loss. This prevents drift in vertical or safety-critical axes.
What protection level enables reliable servo performance in exposed or semi-sealed machine zones?
The motor is IP65-rated, shielding against dust and water spray. It remains operational in splash-prone or dusty industrial setups.
How does this model respond under sustained low-current load applications?
It delivers 1.26 A continuous current for stable torque output. This ensures thermal balance in energy-sensitive or compact designs.
What performance consistency can be expected at low rotational speeds?
It operates at 2000 min⁻¹, supporting controlled, accurate motion. This is ideal for indexing systems or fine-positioning axes.
How does the torque constant impact drive tuning and control loop precision?
With a 0.22 N·m/A torque constant, it delivers predictable torque per amp. This simplifies tuning in torque-sensitive closed-loop configurations.
