SPACE-CONSTRAINED ENGINEERING

DESIGNED AROUND YOUR ENVELOPE / 01

Ultra-flat pancake motors.
For space-constrained engineering.

Pancake motor solutions for space-constrained engineering. Start with thickness, diameter and torque. Build from a magnetic assembly to a complete motion package.

01 / AXIAL THICKNESS02 / OUTER DIAMETER03 / USEFUL TORQUEMAGNET → MOTOR → YOUR MACHINE

The drawing comes first

The motor is only as thin
as the assembly around it.

End turns, bearings, cable bends and feedback hardware all consume axial space. Define the complete installed envelope before choosing an electromagnetic layout.

FRAMELESS / EMBEDDED

Frameless Pancake Motor Kits ↗

Build the motor into your joint instead of building the joint around a motor. Rotor and stator kits leave bearings, housing and cable routing under your control.

HOLLOW SHAFT / THROUGH BORE

Hollow-Shaft Pancake Motors ↗

Route services through the axis while keeping axial height under control. Define the clear passage, shaft support and cable path as one mechanical envelope.

CORELESS / LOW INERTIA

Coreless Pancake Motors ↗

Review an ironless active winding when low inertia and smooth motion matter as much as installation depth. Compare the complete thermal and control system before selecting the winding.

SLOTLESS / PRECISION MOTION

Slotless Pancake Motors ↗

Specify smooth motion at the axis, with slotless winding options for optical positioning, inspection and precision handling in a shallow package.

48V / MOBILE PLATFORM

48V Pancake Drive Modules ↗

Keep a low chassis without losing sight of starting duty. Review a shallow motor or drive module against wheel load, bus range, ramp conditions and repeated acceleration.

Three installation problems

Built around the motion you need.

Prepare a joint, routing, scan or wheel-duty brief →

Pancake Motors for Cobots & Exoskeletons

Keep the joint shallow, preserve the cable passage and specify backdrivability at the complete joint. Start from the mechanical section and human-interaction duty.

Pancake Motors for Low-Profile AGV & AMR Platforms

Build around the chassis height available after the battery and payload are placed. Evaluate direct wheel drive and shallow side-mounted layouts against starting torque.

Pancake Motors for Precision & Optical Equipment

Lower the axis package while keeping velocity ripple, thermal drift and contamination requirements visible. Review slotless or coreless construction against the measurement task.

Rare earths to real assemblies

The magnetic circuit
is part of the package.

Bring magnet geometry, retention, stator laminations and winding support into the same DFM review. Our sourcing focus connects Ganzhou rare-earth materials with precision motor integration.

Three decisions before a motor quotation

Does pancake mean axial flux?

Pancake describes a short, wide form factor. The electromagnetic architecture can vary. Begin with installed depth, available diameter and torque-speed duty before selecting a topology.

Is the thinnest motor always the best fit?

No. Bearings, encoders, cooling and cable exits determine the complete package. A slightly deeper motor can sometimes produce a simpler installed assembly.

What information makes an inquiry actionable?

Share maximum installed thickness, maximum outer diameter, minimum clear bore, continuous and peak torque, speed, voltage, duty cycle and a drawing or controlled CAD link.
