Engineering information for Catalog DA 12 · DC Motors Introduction Siemens DC machines are used wherever power saving technology and high availability are required. Due to their high output density with small outside dimensions and their modular installation, they perfectly fit into even the smallest installation space. Due to the stepless adjustable speed, the drive can be optimally adapted to the respective conditions of use. Together with the digital SIMOREG DC MASTER converter, the DC drives can be found in all industrial sectors all over the world. DC technology is used in rolling...

Structure of standard DC motors Standard air flow direction from non-drive end to drive end for intensive commutator ventilation, air flow direction from drive end to non-drive end also possible. Derating possibly required.

DURIGNIT 2000 insulation system The insulation consists mainly of plastic materials with a high thermal overload capacity and resistance to tracking. It also meets the requirements placed on motors that are operating in tropical conditions (humid and hot climate). Temperature class 155 (F) (overtemperature limit 105 K at a cooling medium temperature of 40 °C) is used for 1G.5/1 H.5 motors. The output must be reduced by 13% to 87% when the motors are used in accordance with temperature class 130 (B). Temperature cIass 180 (H) (overtemperature limit 125 K at a cooling medium temperature of 40...

Supply, converter connection, armature voltage and smoothing reactor The rated voltages specified in the selection tables are standard voltages in accordance with DIN 40030. The ratings at these rated voltages are only valid in conjunction with the specified converter connection and supply voltage. All inductance values specified in the “Selection and ordering data” tables of Catalog DA 12 ■ 2008 are at 100 Hz, for singlephase and at 300 Hz, for three-phase bridge circuits. Assignment of armature and rated voltages to supply voltage and converter connection Non-standard voltages and...

Speed and speed control DC motors are operated within the armature control range until The speed-output diagram shows the relation between they reach the rated speed n\|. In this case the motor speed n is Voltage V Current I, Output P Torque Mand Speed n. approximately proportional to the armature voltage V. Furthermore the machine can be operated by field weakening, i.e. by reducing the field current to the maximum field weakening speed nFmax, respectively to the mechanic speed limit nmech. n N Rated speed n Fmax Max. field weakening speed at PN = constant n mech Max. permissible operating...
