Frequently Asked Questions

What is the impact of motor balancing “Standard” on vibration and long-term operation?

Standard balancing typically reduces major imbalance sources but is less precise than “precision” balancing; for high speed or very sensitive machinery (robotics, high precision packaging), residual imbalance could still cause vibration, bearing wear or noise.

How does the holding brake & continuous stall torque interplay under frequent stop-start operation?

Frequent stops put stress on the brake, which must engage and hold under load often; also, each stall (holding 3.7 Nm at zero speed) draws current and generates heat, so both brake life and thermal capacity of motor/drives must be verified for the expected stop-start duty cycle.

What are the consequences of the keyway shaft type for coupling and backlash?

A keyway shaft (per DIN standards) ensures positive mechanical coupling and high torque transmission without relying on friction alone; however, keyway introduces stress concentration, so shaft and coupling must be well-fit and aligned, and backlash in coupling should be minimized for precision motion

How does having a shaft seal influence maintenance and environmental use?

The seal helps exclude dust, dirt, and some moisture ingress, improving lifespan in harsher environments; but seals can add friction, and over time may wear, so you might see slight increases in torque required or dropped efficiency—seal maintenance or replacement might be necessary.

How does the nominal speed of 2000 min⁻¹ limit or enable dynamic performance (acceleration / deceleration)?

At 2000 rpm, the motor can respond fairly fast, but acceleration torque must overcome inertia; if your loads or mechanical linkages are heavy, you’ll need a drive that can supply enough current (beyond continuous torque) to handle transient torque demands.
