1. Specifications, performance, ratings, and price can change without notice.
Specifications, ratings, and performance quoted for whole of motor at 293 K (20C)
except where noted.
2. 111 rad/s 1060 rpm.
3. Nm  lb ft 2294 oz in.
4. Continuous torque is at maximum, winding, temperature.
5. EMF sinusoidal. Other EMF constants available
6. Current sinusoidal and synchronised to rotor position. Other torque constants
available.
7. Excludes external windage etc., see and
‘.au/Machines/papers/iwscem/’ for details.
8. Total temperature rise having already temperature stabilised at the nominal rating
and then run for a further 72 s at Nm and 111 rad/s.
9. Due to the low inductance of the motor, most motor controllers will require additional
series inductance (3 will be supplied).

The main issues in interfacing a given controller are:
The motor has three phases
The motor requires the applied voltage to be synchronized with rotor position
The position information is provided by three sensors with open collector outputs,
that are suitable for operation in the range 5 to 15 V, see below for more information
A thermist
