Xierke Advantageous Supply Winkelmann GNFZE Motors

The Winkelmann GNFZE motor series, supplied by Xierko, is known for its durability, high overload capacity, and precise speed control. It is widely used in heavy industry fields that require high starting torque and wide range speed regulation.

The Winkelmann GNFZE motor design provided by Xierke Advantageous allows for short-term rated current overload of up to 200% -300%, suitable for working conditions with frequent start stop or severe load fluctuations. Has a starting torque of *, ensuring smooth starting even under heavy loads. DC motors naturally have excellent speed regulation performance, and when combined with modern DC drivers, can achieve a wide range of stepless speed regulation from zero speed to base speed or above.

High speed stability, less affected by load changes.

High dynamic response:

The optimized design of rotor inertia enables the motor to have fast acceleration and deceleration capabilities, making it suitable for drive applications that require high dynamic performance.

Easy to maintain:

Modular design makes the electric brush system easy to inspect and replace.

The bearing has a long service life, and some models are equipped with oil injection nozzles for easy daily maintenance.

Adapt to harsh environments:

Different protection levels (IP23, IP54, IP55, etc.) can be selected to adapt to environments with high dust, humidity, or slightly corrosive gases.

The insulation level is usually F or H, with good heat resistance.

3. Materials&Construction

Stator and rotor iron core:

Made by stacking high-quality and low loss silicon steel sheets, reducing eddy current losses and improving efficiency.

The iron core is precision machined to ensure uniform air gap and reduce noise and vibration.

Winding material:

The armature winding and excitation winding are both made of high-purity oxygen free copper wire, which has good conductivity and low heat generation.

The insulation material complies with international standards such as IEC 60034, and is resistant to high temperatures and corona discharge.

Commutator:

Adopting high-density and high wear resistant copper alloy commutator blades, the surface is precision machined and polished to ensure good contact with the electric brush and low spark level (usually up to 1.5 or better).

Electric brush system:

Equipped with high-performance graphite brushes, with good self-lubricating properties, low wear rate, and small commutation sparks.

Constant pressure spring design ensures stable brush pressure and extends service life.

Shell and structural components:

The machine base is made of high-strength cast iron or welded steel structure, with high rigidity and good heat dissipation performance.
