Kiwi Drive Systems · Machines

One platform. A whole range of machines.

Every machine on this page is built on the same Kiwi Battery Pack, and almost all on the same 1.5 kW motor and controller. Develop the drive once, build a range on it. Choose the machine that belongs in your catalogue and we develop it with you, in your brand and your colours.

The common part

Follow the pack

The Kiwi Battery Pack is the same part on every machine on this page. On a sander its weight is working pressure. On a scrubber it leaves the chassis free for tanks.

Sanding and grinding

Weight is the tool

A sander or grinder works through its own weight. On these machines the battery is part of that weight, centred above the tool, instead of a box carried on the frame.

KIWI400 light and hybrid

The machine the platform started in.

The KIWI400 is our own single-disc floor machine, designed around the Kiwi Battery Pack. The light version carries a sanding head. The hybrid version carries a planetary head and our hybrid module, so it can also run on mains power. Two working prototypes, still with an earlier motor and pack, are on video.

  • Weight where it works. The pack sits around the motor, so its weight becomes pressure on the tool.
  • Battery or socket. The hybrid can also run on mains power.
  • One system. Pack, controller and machine on one CAN bus.

Also in development

In development

Compact floor machine

A compact walk-behind floor machine on the same pack and 1.5 kW motor.

In development

Tilting-head grinder

A walk-behind grinder whose head follows the floor. We built this principle into our mains-powered Kiwi 400R in 2020; now we are reworking it around the pack.

In development

Rectangular-plate sander

A rectangular orbital plate for work along walls and into corners, built on parts of the KIWI400 light.

In development

Parquet belt sander, hybrid

A parquet belt sander on the Kiwi platform, for battery or mains power.

Floor cleaning

The chassis stays free

A compact scrubber needs its chassis for tanks, suction and squeegee. With the pack on the head, around the motor, the chassis stays free and the battery's weight becomes brush pressure.

In development

Two-head scrubber

A compact walk-behind scrubber with two heads, designed around the Kiwi Battery Pack.

In development

Battery vacuum

A compact battery vacuum on the same Kiwi Battery Pack.

Concrete finishing

No engine, no cord

Fresh concrete, often indoors. No place for exhaust fumes, and no place for a cable dragging through the surface.

Design

Battery trowel

A power trowel you fold up and wheel away.

A walk-behind power trowel for finishing concrete floors, driven by our 1.5 kW motor through a gearbox. The pack sits low around the motor, with its weight over the blades.

  • Folds to about half its height. The handle folds down flat for transport.
  • Rolls on its own wheels. Tip it back and wheel it like a hand truck. While you work, the wheels are clear of the floor, and the wheel set comes off with one pin.
  • Open cage, no hood. You see the blades and the concrete and work close to the edge. The pack sits in the open and lifts straight up and out.

The platform

Inside every machine

Pack, motor and controller, engineered together. The machine builder designs around one module.

Kiwi Battery Pack

Lithium iron phosphate cells in a pack shaped around the motor. 48 V, 1.5 kWh, with a 1.0 kWh version in development. Fixed or swappable. Patent pending.

1.5 kW motor

Permanent-magnet motors in two speeds, 1500 rpm and 3000 rpm. Same flange and shaft, so one machine design can take either.

Matched controller

A sine-wave controller characterised for both motors. Pack, controller and machine on one CAN bus.
