English term or phrase: E.M. with variable speed
2.1 Booster compressor packages
2.1.1 Introduction
The purpose of the Booster Compressor Packages is to treat natural gas in accordance with the requirements listed in the following point 3.1
2.1.2 Package
Package consists of :
• Inlet scrubber equipped with liquid level control devices and pressure relief valves(2 interlocked for each scrubber)
• Reciprocating compressor in 2 compression stages (for a better smooth running) driven by E.M. with Variable speed (VFD) to control the flow from 75% to 100% of the rated value.
• Air coolers on each compression stage delivery to get back a temp of 55°C
• N 2 Aftercooler scrubbers equipped with liquid level control devices and pressure relief valves (2 interlocked for each scrubber).
• A recycle Piping to control the flow from 75% to 0%
• ESDV valves at Process gas inlet and outlet and at common drain outlet

ну или если смотреть по тому, что в скобках (VFD), то можно написать "частотно-регулируемый электропривод", что, собственно, по сути одно и то же.

e.m. with variable speed
электродвигатель с ЧПС (частотным преобразователем скорости)


Explanation:
Электродвигатели переменного тока не способны изменять скорость изменением напряжения. Это несколько обобщенно, т.к. есть синхронные и асинхронные машины переменного тока. Поэтому для изменения скорости вращения в небольших пределах применяют изменение частоты питающего тока. Конечно, преобразуется частота, а не скорость, но такой термин уже устоялся. VSD (variable speed drive) = VFD (variable frequency drive). Обычно называют "частотными преобразователями" ил даже "частотниками". Правильнее и профессиональнее нужно говорить "преобразователь", но иного можно встретить и "привод" в отечественной литературе.
