DC  Motor Z315-Z710 reversing mill's drive

Description of DC Motor Z315-Z710:
This series DC motors are specially designed for the reversing mills. The excellent electromagnetism load can reach the best for the optimization of the rotor diameter. In addition these DC motors deliver the required torque while minimizing the inertia of the drive-train. This act make the DC motors quick response to speed and load changes.

Configuration and Features of DC Motor Z315-Z710:
1. Multiple armature winding types to meet different applications.
2. Excellent commutator and brush holder provide premium commutation
3. The pedestal is made from laminated armor plate, mounted with stator frame to ensure the high stability.
4. The TIG-welding is applied to connect the commutator risers and armature coils for maximum connection strength.
5. Exceptional reliability, the DC motor adopts full compensating windings to supply proper compensation for armature reaction.
6. F class VPI (vacuum pressure impregnate) insulation for stator and rotor to withstand moistures, abrasion, and thermal cycling. This make the DC motor can be used in some severe environment.
7. Armature lamination and pedestal feature by paint coating laminated steel frame to improve following ability of electromagnetism, resulting in better commutation.
8. Adopt end bracket type grease ball bearings. The sliding bearings are available.
9. For the standard model, the outlet box is located in the right side (see from the rotary side), it also can be designed in the left side.

Performance of DC Motor for Reversing Mills:
1. Power supply can choose direct current or supplied by the stationary rectifier power.
2. The designed motor rating duty: continuous operation based on S1 duty type
3. The standard rated voltage: 220V, 330V, 440V, 550V, 660V, 750V, 850V for choice. The other rated voltage can be adopted on request.
4. The basic excitation type is separated excitation. Four excitation winding terminals are divided into two groups. The excitation voltage is 220V when the two groups are in serials, otherwise, in parallel connection, the voltage become 110V. Other excitation voltage is available. And the forced excitation is allowed while voltage is less than 500V. When adopts the forced excitation, the excitation current is allowed to exceed the rated excitation current slightly until the excitation current goes to stabilization.
