Description
A permanent magnet rotor spends no energy on excitation and has no slip losses, so efficiency is higher than that of an induction machine and power density is greater. The housing is welded steel, shaft height 355–500 mm, 8–16 poles. Heat is removed by the IC71W water jacket, which reduces maintenance. Bearings are rolling or sleeve, mounting B3 and V1. Supply is from a frequency converter only, and the frequency is selected for the task. An explosion-protected version is not provided for this variant of the series, unlike the induction Compact. The machines are made and tested to IEC/EN 60034 at plants in Germany.
How to choose
The main criterion here is low speed, since the range 0–1000 rpm covers powers up to 1.5 MW. If a combination of a high-speed motor and a gearbox is installed now, a direct PM drive removes the transmission together with its losses and maintenance. The pole count of 8–16 and shaft height of 355–500 mm are selected for the required torque. For a water-cooled induction machine of 37–5500 kW there is the W4.B / WE.B series.

FAQ
Which machines is a permanent magnet motor suitable for?
For low-speed pumps, mixers, conveyors, extruders, marine and mining machinery where it pays to do without a gearbox.
Is a gearbox needed with such a motor?
No, the range 0–1000 rpm makes it possible to couple the motor to the machine directly.
Can the motor be connected without a frequency converter?
No, the motor works only from a frequency converter. Voltage 0.69 kV, and the supply frequency is selected for the task.
How is the motor cooled and what is its protection degree?
By an IC71W water jacket, protection degree IP55. Welded steel housing, mounting B3 or V1.
What shaft height and number of poles does this motor have?
Shaft height 355–500 mm, number of poles 8–16, power up to 1.5 MW.
