(SAE A / Low RPM Torque / OEM Integration Ready)

Hydraulic power packs and pump systems need motors that can handle heavy loads, provide high starting torque, and run smoothly even at low speeds. The Innotec High Torque Hydraulic Pump Motor Platform is designed especially for these demanding systems. Built for OEM integration, it delivers continuous torque, comes with SAE A 2-bolt mounting, and features a 9T 16/32 DP spline shaft output. This allows direct pump coupling, removing the need for belts and reducing alignment problems or power loss.

These high torque motors are perfect for hydraulic drive units, compact power packs, agricultural loaders, skid steer systems, and industrial press equipment. Unlike hobby-grade solutions, they are built for continuous industrial performance, offering strong and reliable power for real-world hydraulic applications.

Low-Speed, High Torque for Hydraulic Systems

Hydraulic pumps usually operate between 500 to 2000 RPM. Many regular motors lose torque in this range, causing performance issues. The Innotec high torque motor maintains strong torque at low RPM, helping the hydraulic system build pressure smoothly without overheating or stalling.

These motors are ideal for:

If you need consistent performance at low speeds, these motors deliver steady torque and reliable operation in every use case.

SAE A Flange and Spline Shaft Compatibility

To make direct pump mounting simple and reliable, these motors are available with standard SAE A 2-bolt face flanges. They include a 9T 16/32 DP involute spline shaft designed for direct hydraulic pump connection.

Technical Interface Options:

  • Flange Standard: SAE A 2-bolt face (optional SAE B available)
  • Output Shaft: 9T 16/32 DP spline (ready for pump coupling)
  • Alignment: Precision-machined face for secure sealing
  • Custom Options: Keyed or alternate spline profiles available

This setup ensures perfect fitment with your hydraulic system while minimizing vibration and wear.

BLDC Efficiency Advantage Over Traditional Hydraulic Motors

Traditional hydraulic systems often run continuously under high pressure, wasting energy. In contrast, BLDC high torque motors use electronic control to deliver torque only when needed, reducing energy loss by up to 20%.

Here are the main advantages:

  • Lower current draw and less strain on power supply

  • Reduced oil turbulence and heat generation

  • Smooth torque control with electronic modulation

  • Compatible with Curtis, ZAPI, and other industrial controllers

This means your hydraulic system runs cooler, quieter, and more efficiently.

Gear Reduction and Coupling Options

Some hydraulic setups, like high-pressure presses or agricultural cutters, need even higher startup torque or shock absorption. For these applications, optional gear reduction interfaces and coupling sleeves can be added.

These accessories help manage load surges smoothly and extend the system’s service life.

OEM Supply — Export Ready for Global Manufacturers

Innotec supplies these motors to OEM hydraulic equipment builders and power pack manufacturers worldwide. The motors are engineered for quality and performance, backed by OEM-friendly manufacturing and export logistics.

OEM Benefits:

  • MOQ flexibility for prototypes or pre-production runs

  • CE and UL compliance available on request

FAQ — Common Engineering Questions

Yes. With an SAE A flange and spline shaft output, a BLDC high torque motor can directly replace hydraulic pump motors while providing better energy efficiency and lower heat generation.

 

The standard configuration uses a 9T 16/32 DP spline, which is compatible with most hydraulic gear and vane pumps. Custom shafts are also available.

48V is the most common choice for OEM hydraulic systems. However, 24V motors are ideal for compact mobile units, while 72V models suit heavy-duty hydraulic packs.
