The XQ-4.5-1KS 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 48V battery forklifts, tow tractors and AGV drive wheels 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-4.5-1KS is rated 1800 rpm at 4.5 kW (6.0 HP) on a 48V battery, with B35 foot-and-flange mounting for a rigid, flange-coupled installation. For 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-4.5-1KS?
A: Yes. OEM/ODM supported — 24V/48V/72V versions, B35 foot-and-flange mounting (B3 foot or B5 flange variants available), and shaft dimensions can be customized. Send your spec to our engineering team.
Q: What is B35 mounting and which vehicles use it?
A: B35 combines a foot base with a flange output, giving both rigid footed installation and a flange-coupled gearbox or wheel hub. It suits electric forklifts, tow tractors and AGVs where a stable footed mount with a flange drive is required. IP44 protects against splashing water from any direction.
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.
