Product FAQs

Q1: Why is an 8kW DC series-wound motor highly recommended for heavy-load startup equipment?

A1: The XQ-8-3KS2 features a series-wound configuration where the armature and field windings are connected in series. This layout excels in heavy-duty applications because starting torque is proportional to the square of the current. With a rated current of 135A, this 8kW motor delivers a massive initial torque burst. It handles heavy-load startups easily without stalling, which is ideal for winches, cranes, and heavy material handling vehicles.

Q2: What are the benefits of the B35 mounting type with bottom corners for this motor?

A2: The B35 mounting specification is a versatile hybrid design that combines both a front flange and foot mounting (bottom corners).

• The bottom foot mounts absorb the massive structural vibration and torque reaction generated by an 8kW motor, ensuring rigid stabilization.

• The front flange allows for a seamless, direct connection to gearboxes, hydraulic pumps, or transmission systems. This dual-support setup provides maximum mechanical stability under severe operating conditions.

Q3: How should the S2-60min duty cycle be managed in continuous heavy-duty operations?

A3: An S2-60min duty cycle indicates a short-time duty rating. The motor can operate safely at its full 8kW rated power for up to 60 minutes continuously. After this peak operating period, it must be shut down to cool down to ambient temperature. Because it is built with an IP44 rating and a robust carbon brush commutation system, it is highly reliable for intermittent, high-power jobs like rail vehicle shifting, street sweeping, or heavy winching operations.
