描述:

The SDN and SDM4 series synchronous electric motors are designed to drive constant-speed mechanisms. This model operates in synchronous mode and is used in power generation and heavy engineering. The motor ensures high efficiency over long periods of operation.

概观:

1. Purpose

They are designed to drive pumps, fans, smoke exhausters, crushers, mills and other mechanisms with difficult starting conditions.

2. Designs (engine types)

Designation	Transcript
SDM	synchronous mill electric motor (Z) – closed
SDN	synchronous electric motor of normal design (З) – closed, “2” – series number
SDS	special design synchronous electric motor (З) – closed
SDE	synchronous electric motor for excavators, (2) – series number
DSM	modernized synchronous motor

3. Main technical characteristics

Parameter	Meaning
Power	400 – 3150 kW
Rotation frequencies	166.7 – 1500 rpm
Supply voltage at 50 Hz	6000 V, 10000 V
