Key Materials and Components

▔▔

• Shaft Sealing Ring: High-performance FKM (Viton) radial sealing ring, delivering high wear resistance and oil-spray tolerance against hydraulic fluids.
• Permanent Magnets: High-grade NdFeB (Neodymium Iron Boron) rare-earth magnets, featuring high thermal stability and resistance to demagnetization under peak load currents.
• Winding Insulation System: Class 155 (F) copper wire insulation and impregnating resin, preventing short circuits under prolonged thermal stress.
• Optical Encoder Module: High-precision optical scale assembly sealed inside heavy-duty aluminum housing to protect electronics from vibration and oil mist.
• Housing Enclosure: Cast aluminum housing with precision anti-corrosion coating, offering fast heat dissipation and structural strength under high torque peaks.

Packaging and Transport Protection

▔▔

• Individual Protection: Vacuum-sealed anti-static and anti-moisture VCI foil packaging with desiccant packs inside.
• Shock Absorption: Custom-fitted high-density EPE molded foam inserts surrounding the motor body, encoder end-cap, and drive shaft.
• Shaft Protection: Rigid plastic protective sleeve installed over the motor extension shaft and keyway.
• Outer Container: Heavy-duty reinforced double-wall corrugated carton for single unit export, or wooden pallet case with heavy-duty banding for batch orders.
• Batch Shipping: Palletized packaging wrapped with multi-layer stretch film and strapping bands to eliminate shifting during ocean or air transport.

Applications

• Servo-Hydraulic Variable Speed Pump Units: Used as the primary drive motor powering internal gear pumps or axial piston pumps, providing direct pressure and displacement modulation to achieve up to 70 percent energy savings compared to conventional constant-speed hydraulic power units.
• Hydraulic Injection Molding Machines: Controls the injection axis, mold clamping cylinder pressure loops, and screw plasticizing functions with rapid velocity acceleration and smooth hold-pressure transitions.
• Precision Hydraulic Bending Presses and Shears: Drives the upper beam positioning axes and proportional servo valves, ensuring micron-level stroke repeatability and precise press-force control.
• CNC Machine Tool Hydraulic Tool Clamping and Axis Drives: Provides stable, continuous torque for hydraulic tool-unclamping power units and rotary feed tables.

FAQ

Q1: How do I verify and decode the full MSK061C model number code?

A1: The model code specifies key parameters: MSK = Series, 061 = Motor Frame Size, C = Length, 0600 = Winding Code, NN = Cooling Method (Natural Convection), M1/S1 = Encoder Type, UP/UG = Shaft Type and Holding Brake Option. Please check the nameplate on your existing motor or consult our team before ordering.

Q2: What are the maintenance requirements for hydraulic oil cleanliness when MSK motors are combined with servo pumps?

A2: For integrated servo-hydraulic pump systems driven by MSK061C motors, hydraulic fluid cleanliness must meet ISO 4406 standard 18/16/13 or cleaner (filtering accuracy equal to or finer than 10 microns) to prevent pump wear and seal degradation.
