Internal Coupling Motors

The technology with integrated coupling, enables even more compact installation of servo motors.

The patented technology Coupmotor® with integrated coupling, enables even more compact installation of HDD motors.

The motors are available in 90 – and 140 mm frame sizes, in a torque range from 2.3 Nm to 10 Nm, rated 3000 rpm and wound for 230 or 400 VAC. All motors can be supplied with or without brake.

The standard motor is equipped with straight connectors, resolver feedback, PTC thermal sensor and IP-65 protected.

As options the motor can be ordered with a variety of feedback systems, angled connectors, IP-67 protected and with pressurized air connection.

Two types of couplings are presently available, both using metal bellows. They are named CBC and CBE. There are two bellow lengths that accommodate run-outs of 0.2 and 0.3 mm respectively.

  • Both lengths have a stiffness of approx. 9 kNm/rad.
  • The CBC model uses a single screw to clamp around the machine shaft. It can be delivered to fit shafts from 5 to 20 mm.
  • The CBE model uses an expanding shaft. The standard diameter of the expanding shaft is 16f7. Other shafts are available on request.
