Industrial DC Commutator Electric Motors and Servo Drives by WAMEL
WAMEL Silniki Elektryczne Sp. z o.o. has engineered and manufactured small and medium-power commutator electric motors (up to 8 kW) in Poland since 1945.
Operating its primary manufacturing facility in Janki near Warsaw, the company produces robust drive units for machine tool feeds, intralogistics platform trucks, medium/high-voltage switchgear mechanisms, and specialized medical and textile equipment.
The flagship K-series permanent magnet DC servomotors (models K 7707 to K 7722) deliver continuous rated torques up to 27 Nm and peak stall torques up to 252 Nm under severe operating conditions.
Each motor integrates an analog DC tachogenerator PATO 78-14 with a calibrated gradient of 31.5 V per 1000 rpm, with optional factory-fitted internal 24V or 90V electromagnetic holding brakes.
Engineering Selection of PZSO Traction Motors and PSSO Switchgear Actuators
Selecting the correct WAMEL electric motor requires matching the power rating, supply voltage, duty cycle, and mechanical flange interface.
For industrial battery platform trucks (such as WNA-1320 vehicles), the series-wound PZSOa 24-85 (2.0 kW, 80V, 33.8A, 810 rpm) and PZSOb 24-85 (2.5 kW, 80V, 40.6A, 1000 rpm) motors provide rugged S2-30min short-time performance and superior breakaway torque.
For switchgear spring-charging mechanisms and substation automation, WAMEL provides PSSO 110-70 motors (110V or 220V) and heavy-duty PSSO 128a (5.3 kW) hydraulic pump motors.
Compact PRMO series permanent magnet flange motors (up to 300W) offer linear armature voltage speed regulation across 12V to 230V systems. SpareX coordinates direct factory-backed deliveries across global industrial markets.
Factory Procurement, Quality Assurance, and Replacement Spare Parts
All WAMEL motors, servodrives, and PATO tachogenerators are delivered in original factory packaging accompanied by technical inspection certificates and manufacturer test logs.
Prior to dispatch, each motor undergoes comprehensive verification covering armature winding resistance, stator insulation integrity, shaft runout tolerances, and tachogenerator output linearity.
To support continuous equipment lifecycle management, SpareX supplies standard factory spare assemblies: brush holders, carbon brush pairs, wound armatures with commutators, end shields, and brake discs.
Direct international logistics agreements ensure authentic origin, transparent commercial documentation, and compliance with manufacturer specifications.
