The A6VM is a variable displacement axial piston motor built on the bent-axis principle. The cylinder block and pistons sit at an angle to the output shaft. Oil pressure pushes the pistons against the drive flange, and that force becomes torque at the shaft.

Why Bent-Axis Design Suits Waste and Biomass Machinery

Built for shock and torque spikes

Komptech's core machines process material that is anything but consistent: green waste, wood, bulky waste, compost, and the occasional piece of rebar that never should have been in the feed. That creates sudden load peaks. Bent-axis motors handle these well because of their sturdy bearings and the geometry of the piston-to-flange connection. The design is generally regarded as more tolerant of shock loading and shaft side loads than swashplate alternatives.

Efficiency across the operating range

Efficiency matters more than most operators assume. In a diesel-hydraulic machine, every percent lost in the drive becomes heat and fuel. A variable motor lets you run the displacement that matches the task, instead of throttling flow and burning energy as heat.

Low-speed, high-torque capability

Slow-turning cutting shafts and heavy drums need serious torque without a gearbox. At maximum displacement, an A6VM delivers that directly. When the material clears or the machine idles through a lighter pass, the motor can swivel back and spin faster.

Where the A6VM Fits in a Komptech Machine

Shredder rotor drives

Slow-speed shredders such as the Komptech Terminator or Axtor class depend on high, stable torque at low rpm. A variable motor allows an operator or controller to trade speed for torque as the feed changes. For example:

Heavy, bulky waste or timber: high displacement, low speed, maximum torque

Lighter mixed material: lower displacement, faster rotor, higher throughput

Screening drums and star screens

Trommel and star screens (the Terra Select and Multistar families, for example) need steady drum or shaft speeds under varying material loads. Variable displacement helps hold the target speed when the load shifts, and a speed sensor option can feed back to the control system.

Windrow turners and conveyors

Compost turners and conveyor systems have a mix of high-load and cruise phases. A variable motor handles both without oversizing the pump or the motor for the worst case.

Q1: How do I know which A6VM my Komptech machine uses?

A1: For motors with catastrophic internal damage or shaft and bearing wear, replacement is often more reliable. For moderate wear in a high-value size, a certified rebuild with test documentation can be cost-effective.

Q2: Should I rebuild or replace?

A2: On the nameplate attached to the motor housing. It lists the type designation and material number, which you'll need when ordering parts.

Q3: What is the price and delivery time of the Rexroth A6VM motor for the Komptech Engineering Equipment?

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
