What You Should Know About Frameless Torque Motor?
A frameless motor is a typical motor that lacks the shaft, bearings, housing, and end bells but actively produces torque and speed. The rotor and stator are the only components of a frameless torque motor.
The inner component, known as the rotor, often mounts directly onto the machine shaft and consists of a rotating steel donut assembly with permanent magnets.
The stator, the exterior component, and the mounts tightly inside the machine housing are made of steel laminations and copper windings around the teeth.
Reason Why Should I Use Frameless Torque Motors?
Modern machines using frameless motors are typically built to have one or more of the following advantages:
Improved machine efficiency
Absence of mechanical compliance
Increased system bandwidth
Increased machine effectiveness
A smaller form factors
More compact machine footprint
Highest torque-to-volume ratio
Decreased maintenance
Less mechanical components
No parts that need replacement or maintenance
The enhanced rigidity that a frameless motor delivers when incorporated into a machine gives it a performance advantage. Dynamic performance is enhanced since there are no mechanical components between the path of the motor and the load. Due to the motor and load are now one inertial mass, inertia matching is no longer as important because there are no mechanical parts to wear out, the lifespan of the entire system is improved, and maintenance costs are decreased.
How Do I Measure a Frameless Torque Motor for My Machine Application?
The same methods used to size a typical, housed servo motor are employed to size frameless motors. The motion requirements for both torque and speed are assessed for the machine application. Due to the absence of gearing, belts, pulleys, or coupling components in the mechanical drive train, a machine created with a frameless motor will typically have better efficiency.
Often, the size of frameless motors is made more accessible by this efficiency. You can usually determine the RMS torque, speed, and peak circumstances needed to choose a motor by knowing the actual machine or part duty cycle timing. You may accurately determine your motor sizing needs with online motion sizing tools.
A frameless torque motorframeless torque motor performance curve tool is also offered, which enables machine designers to comprehend actual motor and drive performance, even at varying bus voltages, operate current restrictions, and ambient temperature ranges.
Instead of selecting from a small winding based on the typical input bus voltage, this tool allows you to optimize the choice of frameless motor winding depending on the real machine's needs.
Applications That Are Suitable for Frameless Motors!
Almost all machine markets employ frameless motors extensively, including robotics, medical, machine tools, packing, printing, converting, and general automation.
In general, the advantages of enhanced machine performance, compact design, and decreased maintenance are appreciated.
Installation of a Frameless Motor
The majority of individuals believe that installing a frameless motor is a challenging task. Typically, slip-fit tolerancing and easily accessible industrial adhesives can be used to install frameless motor components in a simple machine housing design.
Through removing couplings, gearing, and belt modifications, using frameless motor part sets frequently improves manufacturing efficiency and decreases setup times for machines. The system mechanics are now more repeatable, which also cuts down on time needed for system tweaking and commissioning.
