A frameless torque motor is a toroid shaped motor which can directly drive the application without additional mechanics, like worm wheels, belts, or pulleys. They are also called direct drive motors.
Frameless refers to a motor without a frame, housing, bearing or feedback system. As a result, system suppliers are capable of optimizing the motor according to their application and reduce the cost of ownership.
Magnetic Innovations Framless Torque Motors Series are designed to be built in the integral part of a system. With its outrunner and frameless design, size and weight are decreased making the motors easy to integrate and use in various applications.
Because of their shape, frameless torque motors are able to generate a lot of torque, but relatively little RPM compared to conventional servomotors. The latter can reach a much higher RPM, but generate less torque.
To reach the desired speed to torque ratio, a coneventional servo motor is therefore often fitted with a gearbox. This gearing reduces the efficiency and accuracy.
In addition, because of the high specific torque density, frameless torque motors are very suitable for small building volumes.
The Global Frameless Torque Motor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
ALXION rameless permanent magnets brushless torque motors for direct drive – STK Direct Drive motors have been designed for being integrated at the heart of servomechanisms with the aim to improve the performances of axis control of high torque motors.
Thus, the use of ALXION’s Direct Drive frameless torque motors offers adequate solutions regarding the improvement of dynamic performances and accuracy and allows to address applications with demanding constraints on volumes and weights.
It possess Continuous torque from 8 Nm up to 2708 Nm continuous in natural convection depending on size and up to 6100 Nm in fluid cooling and it has Six external diameters from 145 mm up to 800 mm and an Internal diameter from 56 mm up to 630 mm.
It has various option and Various available windings from 30 rpm up to 1500 rpm depending on type. Rotor non dynamically balanced; if needed balancing has to be made by the user on assembled rotor For environment and integration constraints, please request our STK handbooks for assembly ; Frameless design: one rotor and one stator to be integrated inside user’s mechanics.
