Product Description:

The DBL3H00250-QR2-000-S40 Servo Motor from the DBL series is designed and manufactured by Kollmorgen. It delivers consistent performance and operates effectively within a broad voltage range. This motor is designed for durability and long term industrial use.

The DBL3H00250-QR2-000-S40 servo motor supports a mains voltage range between 230 VAC and 480 VAC. At 230V, it delivers a rated torque of 2.2 Nm with a rated current of 2.7 A and operates at 3000 min⁻¹. At 400V, the motor provides a rated torque of 1.8 Nm consuming 2.3 A and yields a rated power output of 1.13 kW. The peak current capacity reaches up to 13 A. The winding inductance is measured at 11.7 mH and the voltage constant is 87 mV/min. It exhibits a static friction torque of 0.05 Nm. The thermal time constant of the motor is rated at 22 minutes which ensures thermal stability during operation. This motor can endure axial loads up to a maximum of 85 N. It supports continuous operation and is built for sustained performance with controlled heating behavior especially when mounted on an adapter flange maintaining + 65 °C.

The DBL3H00250-QR2-000-S40 servo motor has specific derating guidelines based on temperature and altitude. The motor works perfectly fine when used between 40 °C to 50 °C under 1000 MSL, with 1% reduction in rated data. However, the rated data efficiency reduces by 6% when it is used at 2000 MSL and it declines gradually with the further increase in altitude. However, no derating is necessary for sites above 1000 m if the temperature is reduced by 10 K per 1000 m increase in elevation. Get this servo unit now from Wake Industrial.
