Standard Features

DC Motors are newly developed products of our works. The products are found wide use for prime mover in various fields.

DC Motors outline and mounting dimensions comply with IEC72 Standard, except for the axial distance between the mounting holes (dimension B).

DC Motors Performance and technical requirements of the motors can be checked in accordance with IEC34-1 Standard of the International Electro technical Commission, or DIN57530 Norm of the Deutsche Industries-Norm.

DC Motors are class F insulated, with reliable insulating construction and impregnating process, ensuring stable dielectric performance and excellent heat dissipation.

DC Motors possess the features of small size, good performance, light weight, large output, high efficiency and reliability, being able to match the current international advanced level.

DC motors can be lastingly operated form fully controlled three-phase bridge without a smoothing reactor. Motors for 160V may be operated on single-phase bridge thyristor. In that case, a smoothing reactor, whose inductance is specified in the relevant technical date, should be inserted in the armature circuit to suppres ripple current.

DC motors Excitation Type

Separate excitation is the basic excitation type of this series motors, Nominal field voltage: 180V, other excitation voltage are also acceptable on request. To assure the reliability of insulation of excitation system, The motor must be protected against self-induced voltages by a release resistor connected in parallel with the field winding when the excitation circuit of the motor is interrupted, At rated field winding resistance (cold). While the field voltage is higher than nominal voltage, the value of shunt resistance may be lower than seven-time fields resistance. Otherwise higher than seven-times.

Service Conditions

Ambient conditions for motors should be free from acidic, alkali fumes or other aggressive gas which corrode insulation

Armature and field circuits for motors may be either operated on static thyrisier controlled supplies, or from d-c generator

Monthly average temperature would not be more than 24 Degree Celsius. And relative humidity: monthly average no more than 85%.
