If traditional motors are like boxed appliances,
are like custom-built engines—sleek, powerful, and designed to fit perfectly into their environment. As robotics, automation, and precision engineering evolve,
raised frameless motors
are stepping into the spotlight. In this guide, we’ll break down what makes them special and introduce the
if performance and precision are your top priorities.
Frameless motors strip motion down to its essentials. No housing. No bearings. No shaft. Just a stator and rotor—pure torque and precision. This minimalist design gives engineers the freedom to build compact, lightweight, and highly efficient systems without compromise.
A raised frameless motor is engineered with enhanced structural geometry, optimized mounting elevation, or advanced thermal pathways to improve torque output, cooling efficiency, and mechanical stability within integrated systems. Think of it as a frameless motor that’s been reinforced for elite performance.
Unlike traditional motors that come fully enclosed, frameless motors are embedded directly into the machine. The “raised” aspect often refers to higher torque density, reinforced electromagnetic design, or elevated thermal performance.
In high-performance systems, millimeters and milliseconds matter. Raised frameless motors deliver more torque in less space while managing heat more effectively—critical for precision-driven industries.
Frameless motors operate using electromagnetic interaction between the stator and rotor—simple in theory, powerful in execution.
When current flows through the stator windings, a magnetic field is created. This field interacts with permanent magnets on the rotor, generating smooth, controlled rotation.
Torque density is king. Raised frameless motors pack exceptional torque into compact footprints, making them ideal for tight spaces and demanding applications.
Why are engineers obsessed with these motors? Because they solve problems that traditional motors simply can’t.
No housing means no wasted space. Raised frameless motors integrate seamlessly into robotic joints, rotary tables, and gimbals.
These motors offer ultra-low cogging and high-resolution feedback compatibility, enabling buttery-smooth motion control.
Thermal Performance
Better heat dissipation equals higher continuous torque. Raised designs often leverage direct mounting to machine structures for superior cooling.
