The XQ-1.35-5K is a series wound DC motor — the same brush-and-commutator design used in industrial traction drives for decades. The series connection between the armature and field windings gives it the signature advantage for traction work: very high starting torque to break a heavy, stationary load free from rest. That is exactly what a winch needs to start lifting, what an AGV needs to start moving a loaded payload, and what a work cart needs to climb a ramp. As the load lightens, the motor naturally speeds up — a series-wound characteristic that suits equipment with a variable duty cycle. Because high starting torque is the defining trait, this motor is a strong fit wherever a load must be accelerated from zero against resistance. For a 1.35 kW machine on a 72V system, that operating profile is exactly right for light-to-medium AGV, winch and cart duty. The trade-off is brush wear: at 72V 25A, plan on inspecting the brushes every 1500–2000 hours in light-to-medium duty; in heavy continuous duty expect shorter intervals. Brush replacement is straightforward — the brush caps are accessible on the motor housing, no special tools needed.
The XQ-1.35-5K runs directly off a 72V battery — there is no inverter and no DC-DC boost converter in the path. The motor controller just chops the 72V battery voltage to vary the speed, the same way a standard industrial traction controller does. That keeps the drive system simple, the failure modes few, and the wiring straightforward. Two battery pack options pair naturally with this motor: a 72V lead-acid pack (six 12V deep-cycle batteries in series, full charge around 84V) or a 72V Li-ion / LiFePO4 pack (typically a 20S configuration, 72V nominal, full charge around 84V). The motor's 25A continuous draw is well within the rating of standard 72V chopper controllers in the 40–60A class. Set your controller to limit continuous current at 25A (or just above) for the rated load, and size it to handle the start-up inrush — typically 2–3× rated current for a series wound motor.
The XQ-1.35-5K has a rated speed of 1500 rpm at its rated 1.35 kW load. Like all series wound traction motors, its speed varies with load: it slows under heavy load (where torque is highest) and runs faster as the load lightens. The 1500 rpm figure is the rated operating point for sustained work — pulling a loaded cart up a ramp, lifting on a winch, or driving an AGV deck against rolling resistance. Under no-load the motor runs faster, so the controller should be set to limit the top speed to the working range your equipment needs. If your gearbox, drum or wheel needs a different input speed, the winding can be re-tuned for a different speed band — send your spec to our engineering team.
The XQ-1.35-5K uses a foot mount (IEC code B3) with a single output shaft — the motor bolts down to a flat surface via its base feet, rather than bolting to a gearbox flange. That makes it the right choice when the motor is fixed to a frame: a winch chassis, a cart sub-frame, a hoist base, or a stationary material-handling machine. Before ordering, confirm your mounting footprint — the foot bolt-hole pattern and shaft height — matches your existing design, or send us your dimension drawing and we will confirm feasibility. If you need a flange (B5/B14) or double-shaft variant instead, we can build it as a custom order.
The XQ-1.35-5K is rated IP44 — protected against solid objects over 1 mm and against water splashing from any direction. That is a step up from the IP21 rating on our lighter 24V units, and it suits industrial floors, dusty workshops, and light outdoor or washdown-adjacent environments where the motor is not directly hosed down. For full washdown or submerged duty, ask about an IP54 or IP65 upgrade. Pair the IP44 rating with the foot-mount frame and you have a motor that lives comfortably on a job-site cart or a winch exposed to the elements.

The XQ-1.35-5K belongs to the Baoluo XQ series of series wound DC traction motors (standard compliance to be confirmed against the nameplate — please provide the nameplate standard and drawing number if you need them on the datasheet). Mounting dimensions and shaft height follow the series convention, so the motor can be a matched replacement for existing foot-mount DC traction motors in the same 1.35 kW / 72V class. For OEM customers we can customize: voltage variants at the same frame size, terminal box orientation, encoder mounting, IP rating upgrade to IP54 or IP65, and custom shaft diameters or splines. Typical lead time for standard XQ-1.35-5K: 15–20 working days. For custom configurations: 30–40 working days. Send your spec sheet for a quote.
The XQ-1.35-5K needs a 72V DC motor controller (chopper or PWM controller) to vary speed and direction. The controller must be rated for at least 25A continuous current (we recommend 40–60A for start-up headroom) and handle the start-up inrush typical of series wound motors (2–3× rated current). Common controller families that pair with this motor: Curtis, Sevcon, ZAPI, and Chinese OEM controllers in the 40–100A class for 72V systems. For reversible direction the controller needs an H-bridge topology with regenerative braking; for simple on/off speed control with a potentiometer, a basic chopper controller is enough. The motor's Class F insulation (rated to 155 °C) gives plenty of thermal headroom for PWM switching transients. Match the controller's battery voltage to your pack (72V nominal) and confirm the controller's current limit is set to 25A for the rated load.
Q: Is the XQ-1.35-5K suitable for a forklift?
A: At 1.35 kW / 72V it is sized for light-to-medium duty — small AGV, inspection vehicles, electric winches, compact industrial carts. A sit-down counterbalanced forklift typically needs 5–10 kW and 48V or 72V; for forklift-class applications see our 72V XQ-5.5-24DAL (5.5 kW) or XQ-7.5-18FA (7.5 kW).
Q: Do I need a motor controller? Can I connect the XQ-1.35-5K straight to a battery?
A: Direct battery connection will spin the motor up to its no-load speed with no load control — not useful and not safe in practice. You need a 72V DC motor controller (chopper) to vary speed, limit starting current, and control direction. We can recommend specific controller models matched to your load and battery.
Q: How long do the brushes last?
A: For typical series wound motors of this size, brush life is 1500–2500 hours in light-to-medium duty (intermittent AGV cycles, occasional winch use, cart runs). In heavy continuous duty expect shorter intervals. Brush replacement is straightforward — the brush caps are accessible on the motor housing, no special tools required, and replacement brush sets are available from Baoluo as spare parts.
Q: Is the mounting a standard B3 foot mount?
A: Yes, the XQ-1.35-5K uses a standard B3 foot mount with a single output shaft. Confirm the foot bolt-hole pattern and shaft height match your frame, or send your existing motor's dimension drawing and we will confirm feasibility. For a flange (B5/B14) or double-shaft variant, we can build it as a custom order.
Q: What makes this motor good for a winch?
A: A winch needs high torque at start-up to break a load free and pull it up — exactly the high starting torque characteristic of a series wound DC motor. The foot (B3) mount bolts straight to the winch frame, and the 72V battery system is the same pack many industrial winches already use. Size the controller for the peak pull current and you have a compact, simple winch drive.
