The Permanent Magnet Synchronous Machine, Model 8541-1, is the 2 kW variant of the 0.2 kW Permanent Magnet Synchronous Machine, Model 8245. Just like its 0.2 kW counterparts, Model 8541-1 is equipped with a thermistor for measuring the rotor temperature, as well as with Hall effect sensors to determine coarse rotor position. The machine is permanently mounted on a mobile cart, and includes a double-extension shaft terminated with geared-type flanges. It can be joined to different machines using a hard rubber coupling device and patented locking fastener designed to eliminate vibrations.

The Permanent Magnet Synchronous Machine has a specifically high inertia to simulate a high-power machine. The frames of the machine are equipped with transparent shatter-proof shields for inspection of the interior. The insulation class of the machines is B (80E temperature rise), the service factor is continuous, and the construction is of the open type.

All machine windings are brought out to the faceplate of a connection module through a 3 m (10 ft) long, heavy-duty, interconnecting cable fitted with a keyed connector. The Permanent Magnet Synchronous Machine, Model 8541-1, can only be connected to its associated connection module, Model 8542-1. All windings are individually accessible on the faceplate of the connection module associated with the machine. Power windings are terminated by 4 mm color-coded safety jacks, while the thermistor and Hall effect sensors outputs are terminated by 2 mm miniature banana jacks.
