Printed Motor Works redesigned their IR9 internal rotor brushless motors. They have become shorter, lighter with enhanced efficiency. Constructed from fewer components, the upgraded versions are simpler for machines.

Magnetic encoder and electromagnetic brake

The IR9 motors can be fitted with a compact, rugged magnetic encoder for commutation or encoder functions, without increasing the overall length of the motor or adding an external cover. The shaft mounted magnet gives positional emulation of hall switches for motor commutation as well as direction and speed feedback, with 12 bit resolution of rotor position by 4069 counts per revolution. Another option is an electromagnetic brake within the motor casing, which doesn’t require a separate external cover.

Custom Designed

IR9 motors typically have a peak torque of 2 Nm, a rated speed of 3500 rpm and a nominal operating voltage of 62 V., but they can be custom designed to a client's precise specification and are wound specifically for the voltage and current supply required.

Possible applications

Possible applications include marine winch systems, bomb disposal robots, industrial automation, fan drives and paper handling, in sectors such as robotics, materials handling, medical, industrial automation, aerospace and defence.
