The XQ-6.3-3ES is a series wound DC motor — it belongs to the brushed DC motor family. Current is fed to the rotor through carbon brushes and a commutator, which gives very high starting torque and a wide speed range. The trade-off is brush wear: brushes are a normal service item (typically replaced every 1,000-2,000 operating hours depending on duty cycle). Compared with brushless DC motors, brushed DC motors are cheaper and simpler to control — that is why most 72V battery forklifts, AGVs and material handling trucks still use them.
A series wound motor places the field winding in series with the armature, so torque rises sharply as load increases and is highest at standstill. That is exactly what a vehicle needs: strong pull-away from zero speed, then a natural speed increase as the load eases. The XQ-6.3-3ES is rated 1800 rpm at 6.3 kW (8.4 HP) on a 72V battery, with B5 flange-only mounting for a compact, flange-coupled installation. For indoor material handling and towing, this combination delivers the acceleration and overload margin a traction drive demands without the cost of an electronic commutator.

Q: Can you customize voltage or mounting for the XQ-6.3-3ES?
A: Yes. OEM/ODM supported — 24V/48V/72V versions, B5 flange-only mounting (B3 foot or B35 foot-and-flange variants available), and shaft dimensions can be customized. Send your spec to our engineering team.
Q: Is IP21 protection enough for my application?
A: IP21 protects against finger contact and vertically falling water drops — it is rated for indoor and sheltered industrial use (warehouses, enclosed factory floors, dry cabs). It is NOT for outdoor rain, washdown or immersion. If your vehicle runs outdoors or gets hosed down, ask our engineering team about IP44 or higher enclosures.
Q: What is the standard lead time?
A: Standard lead time is 15-25 working days for sample orders and 25-35 working days for bulk orders, shipping from Shanghai or Ningbo port. Confirm exact lead time for your volume at inquiry.
