Asynchronous motor prices depend on far too many variables to be captured by a single list figure, because the price is built up from the sum of technical features that range from the power rating to the frame material. Sound budgeting starts with understanding these factors.

The Main Factors That Set the Price

An asynchronous motor's cost is driven most by power (kW) and efficiency class. Across the 0.55 kW to 355 kW range, the more power, the more material and the higher the price. Efficiency class matters too: IE3 Premium and IE4 Super Premium motors contain more copper and higher-grade steel, so they carry a higher initial price than IE2.

The Effect of Frame, Speed and Mounting

A cast iron frame is more durable but costlier than an aluminium one, and is preferred in heavy industry. Speed also affects price; low-speed 6-pole high-torque models are sized differently from 2-pole models of the same power. The choice of B3 foot-mounted, B5 flange-mounted or B14 face-mounted arrangement is reflected in the cost as well.

Whole-Life Cost Rather Than Price

Looking only at the label price can mislead, because in a continuously running motor the energy cost far exceeds the purchase price over its life. A higher efficiency class, though slightly dearer at the outset, lowers total cost over long operating hours. Price should therefore be assessed together with the consumption profile.
