The XQ-7.5-2S4 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 tow tractors, order pickers 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: a strong pull-away from zero speed, then a natural speed increase as the load eases. The XQ-7.5-2S4 is rated 1200 rpm at 7.5 kW (10 HP) on a 48V battery, with B5 flange-only mounting. The low 1200 rpm rating means high torque at the shaft — ideal for a tow tractor dragging heavy carts or an order picker lifting a platform, where steady low-speed pull matters more than top speed. With IP21 and Class F insulation it is built for indoor warehouse and factory duty.

Q: Can the XQ-7.5-2S4 pull a heavy tow tractor or lift an order picker?
A: Yes. At 7.5 kW (10 HP) on 48V with a 1200 rpm rated speed, this series wound motor delivers high torque at low speed — the exact profile a tow tractor needs to start a heavy cart from rest, and an order picker needs for steady, controlled lifting. Series wound motors produce their peak torque at standstill and taper as speed rises, so they suit load-pulling and lifting far better than a high-speed motor would.
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, factory floors, enclosed cabs, covered loading docks). It is NOT for outdoor rain, washdown or immersion. Tow tractors and order pickers that run indoors are a good fit; if your vehicle works outdoors or gets hosed down, ask our engineering team about IP44 or higher.
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.
