Pain Points vs. Solutions

Challenge: Speed control under different load circumstances is not consistent

Digital DC speed controllers with individually stimulated Z motors provide consistent rpm under changing loads.

Problem: Excessive heat when used at low speed for a long time

Solution: Separate forced-air cooling systems are used to keep the operating temperature at the optimum level under continuous heavy-load situations.

Challenge : Compatibility with current voltage systems

Solution: With many voltage variants (110V, 160V, 220V, 400V, 440V DC) it is a perfect fit for your existing infrastructure.

Technical Advantages

The Z Series Medium DC Motor features advanced armature design with precision-wound field coils for superior electromagnetic efficiency. Series connection of armature and field windings generates high starting torque, essential for overcoming initial inertia in heavy machinery. The motor's current-squared behavior enables automatic torque adjustment based on load demands.

Terminal identification follows industry standards with A1/A2 armature leads, S1/S2 series field connections, and F1/F2 shunt field terminals, simplifying installation and maintenance procedures. Standard protection grades IP21/IP23 ensure reliable operation in typical industrial environments while preventing contamination ingress.

Production Process

Our manufacturing partners employ SAP-integrated factory management systems ensuring quality consistency throughout production. Each motor undergoes rigorous winding accuracy verification, magnetic field balance testing, and thermal performance evaluation. Dynamic balancing procedures minimize vibration, while insulation resistance testing guarantees electrical safety compliance.

FAQ

QWhat does the letter Z represent for Z series DC motors?

AZ is the national standard code for general DC motors in China, short for "Zhi Liu", meaning DC. This general series includes Z2, Z4 and other derivative models.

QWhat excitation modes are available for Z series DC motors?

ACommon types include shunt excitation, compound excitation and separate excitation. Separately excited Z motors are most commonly matched with digital DC speed regulators.

QWhat are the main voltage grades of standard Z DC motors?

AClassic voltages cover 110V, 160V, 220V, 400V, 440V DC. Different voltage models are selected according to the output voltage of the speed controller.

QWhat cooling structures do general Z DC motors adopt?

AStandard self-fan cooling, independent forced air cooling and water cooling optional. For long-time low-speed heavy load, separate forced air cooling is recommended.

QWhat's the applicable working environment for Z series DC motors?

ASuitable for indoor dry, dust-free and non-corrosive gas environment; standard protection grade IP21/IP23, not suitable for flammable and explosive sites without explosion-proof modification.
