Frequently Asked Questions
In what way does the centring diameter of 110 mm impact mounting and coupling?
The 110 mm centering diameter sets the flange size and determines coupling alignment tolerances; precise matching of mating flange or adapter is required to avoid eccentric loads, vibration, and premature wearing of bearings or seals.
What does compliance with EN 60721-3-3 tell about environmental protection?
EN 60721-3-3 relates to stationary environment, classes of weather-protected operating conditions; so the motor can survive in non-sealed enclosures with moderate humidity or dust, but is not suited for full outdoor exposure or wash-down environments without extra protection.
What are the implications of “continuous torque at standstill” being 3.7 Nm?
It indicates how much torque the motor can sustain indefinitely at zero RPM without motion which is critical for tasks like holding loads or indexing; using it beyond rated torque can lead to overheating or insulation damage. It also guides selection of the drive’s current rating and thermal capacity.
How should the holding brake behave under frequent stopping cycles?
The 6.5 Nm blocking (holding) brake is sufficient for maintaining position under load, but in high frequency stop/start or load-changes it may heat up and its friction surfaces will wear; implementing cooldown periods or use of external brake when stationary for long periods is advisable.
What does the high torque-to-inertia ratio imply for motion dynamics?
A favorable torque-to-inertia ratio means the motor can accelerate more quickly with less power overshoot; in practice you’ll see faster response and tighter control for step changes in velocity. It also lowers the load on drive electronics during rapid direction changes.
