电磁式
电磁式直流电动机由定子磁极、转子（电枢）、换向器（俗称整流子）、电刷、机壳、轴承等构成，电磁式直流电动机的定子磁极（主磁极）由铁心和励磁绕组构成。根据其励磁（旧标准称为激磁）方式的不同又可分为串励直流电动机、并励直流电动机、他励直流电动机和复励直流电动机。因励磁方式不同，定子磁极磁通（由定子磁极的励磁线圈通电后产生）的规律也不同。
串励直流电动机的励磁绕组与转子绕组之间通过电刷和换向器相串联，励磁电流与电枢电流成正比，定子的磁通量随着励磁电流的增大而增大，转矩近似与电枢电流的平方成正比，转速随转矩或电流的增加而迅速下降。其起动转矩可达额定转矩的5倍以上，短时间过载转矩可达额定转矩的4倍以上，转速变化率较大，空载转速甚高（一般不允许其在空载下运行）。可通过用外用电阻器与串励绕组串联（或并联）、或将串励绕组并联换接来实现调速。
并励直流电动机的励磁绕组与转子绕组相并联，其励磁电流较恒定，起动转矩与电枢电流成正比，起动电流约为额定电流的2.5倍左右。转速则随电流及转矩的增大而略有下降，短时过载转矩为额定转矩的1.5倍。转速变化率较小，为5%~15%。可通过消弱磁场的恒功率来调速。
他励直流电动机的励磁绕组接到独立的励磁电源供电，其励磁电流也较恒定，起动转矩与电枢电流成正比。转速变化也为5%~15%。可以通过消弱磁场恒功率来提高转速或通过降低转子绕组的电压来使转速降低。
复励直流电动机的定子磁极上除有并励绕组外，还装有与转子绕组串联的串励绕组（其匝数较少）。串联绕组产生磁通的方向与主绕组的磁通方向相同，起动转矩约为额定转矩的4倍左右，短时间过载转矩为额定转矩的3.5倍左右。转速变化率为25%~30%（与串联绕组有关）。转速可通过消弱磁场强度来调整。
换向器的换向片使用银铜、镉铜等合金材料，用高强度塑料模压成。电刷与换向器滑动接触，为转子绕组提供电枢电流。电磁式直流电动机的电刷一般采用金属石墨电刷或电化石墨电刷。转子的铁心采用硅钢片叠压而成，一般为12槽，内嵌12组电枢绕组，各绕组间串联接后，再分别与12片换向片连接。

Installation and Start-up
• The pilot is shipped “cleaned for oxygen service.”
The spark gap is factory-set. Never attempt to
disassemble the pilot.
• Install the pilot by the NPT threads in the burner
housing of the OXY-THERM® LE, or with the bolton
pilot adapter when used on the Standard OXYTHERM
®.
• When threading in the pilot, do not use a pipe
wrench on the tee section; use the stainless nipple
instead. Take care not to damage the stainless fuel
tube when making the connection.
• The 3/16" compression fitting can be removed for
1/8" NPT connection, if preferred. The Swagelock
nut should only be tightened three-quarters of a
turn from finger-tight.
• Refer to the Capacity and Specification chart on
the previous page for recommended pressures and
flow rates.
• Spark should be constant only until the pilot lights.
• Pilot operation should always be interrupted when
used with either the OXY-THERM® LE or Standard
OXY-THERM® Burners. Failure to do so will result
in imbalanced main burner flame and accelerated
degradation of the refractory block.
• Cooling oxygen must be used when the pilot is
installed in a high temperature atmosphere and
the OXY-THERM® Burner is not firing.
• The proper sequence for igniting the pilot is: Spark
on, Oxygen on, Fuel on (ignition occurs), Spark off.
At this point, the main OXY-THERM® Burner can
be ignited. If the burner is not going to be ignited
within a few minutes, the pilot should be interrupted
to extend refractory life.
