Frameless Motors
The IR Series frameless motors are axially compact brushless DC motors with a conventional internal rotor design. They feature a relatively high slot fill resulting in high torque density. We offer two standard sizes, based on stator diameter, the IR9 and IR16 with a range of standard windings and stack lengths. If these standard solutions don’t meet your requirements we will work with you to develop a specification perfectly optimised for your application. PMW’s maximum slot fill manufacturing techniques and access to powerful grades of magnets means that we can optimise your motor to 94% efficiency at your load point. Parameters for motor optimisation are speed, voltage, torque, efficiency, cogging torque and thermal performance.
Applications for the IR Series flat frameless motors include aerospace, defence, robotics, factory & warehouse automation.
Below is a table with some examples from the IR Series internal rotor motor range:
