A PM motor does not have a field winding on the stator frame, instead relying on PMs to provide the magnetic field against which the rotor field interacts to produce torque. Compensating windings in series with the armature may be used on large motors to improve commutation under load. Because this field is fixed, it cannot be adjusted for speed control. PM fields (stators) are convenient in miniature motors to eliminate the power consumption of the field winding. Most larger DC motors are of the "dynamo" type, which have stator windings. Historically, PMs could not be made to retain high flux if they were disassembled; field windings were more practical to obtain the needed amount of flux. However, large PMs are costly, as well as dangerous and difficult to assemble; this favors wound fields for large machines.
What is another name for PM fields?
stators

Valencia was founded as a Roman colony in 138 BC. The city is situated on the banks of the Turia, on the east coast of the Iberian Peninsula, fronting the Gulf of Valencia on the Mediterranean Sea. Its historic centre is one of the largest in Spain, with approximately 169 hectares; this heritage of ancient monuments, views and cultural attractions makes Valencia one of the country's most popular tourist destinations. Major monuments include Valencia Cathedral, the Torres de Serrans, the Torres de Quart, the Llotja de la Seda (declared a World Heritage Site by UNESCO in 1996), and the Ciutat de les Arts i les Ciencies (City of Arts and Sciences), an entertainment-based cultural and architectural complex designed by Santiago Calatrava and Felix Candela. The Museu de Belles Arts de Valencia houses a large collection of paintings from the 14th to the 18th centuries, including works by Velazquez, El Greco, and Goya, as well as an important series of engravings by Piranesi. The Institut Valencia d'Art Modern (Valencian Institute of Modern Art) houses both permanent collections and temporary exhibitions of contemporary art and photography.

By the Treaty of Paris (1763), France regained the five establishments captured by the British during the war (Pondichery, Mahe, Karikal, Yanam and Chandernagar) but was prevented from erecting fortifications and keeping troops in Bengal (art. XI). Elsewhere in India, the French were to remain a military threat, particularly during the War of American Independence, and up to the capture of Pondichery in 1793 at the outset of the French Revolutionary Wars without any military presence. Although these small outposts remained French possessions for the next two hundred years, French ambitions on Indian territories were effectively laid to rest, thus eliminating a major source of economic competition for the company.
The treaty of Paris return how many esablishment captured by the British?
five
