NORD DRIVESYSTEMS SK373.1 IEC71 202496328-100 Motovario NMRV 030 Worm Gearbox Ratio 40:1 with Brook Crompton 0.18kW Motor

NORD Drivesystems Geared Motor Assembly with Mechanical Variator 0.37kW Description This is a complete, high-torque geared motor assembly, ideal for low-speed industrial applications requiring precise mechanical speed adjustment. The unit combines a reliable Brook Crompton 0.37 kW three-phase motor, an efficient Motovario mechanical speed variator, and a robust NORD Drivesystems helical-worm gearbox. This configuration allows for smooth speed control without the need for an electronic frequency inverter. The entire assembly is in excellent, unused condition and ready for deployment. Specifications Power: 0.37 kW (at 50 Hz) / 0.44 kW (at 60 Hz) Motor Speed: 1330 RPM (at 50 Hz) Voltage: 230/400V at 50Hz, 276/480V at 60Hz Gearbox Ratio: 102.01:1 Final Output Speed Range: Approximately 1.86 to 9.31 RPM (calculated) Maximum Output Torque (M2): 261 Nm IP Rating (Motor): IP55 Mounting Position (Gearbox): M5 Label Info Gearbox Manufacturer: NORD DRIVESYSTEMS Gearbox Type: SK 373.1 IEC71 Gearbox No: 202496328-100 Motor Manufacturer: BROOK CROMPTON Motor Type: B-DA71MB-D 4 B5-PTC Variator Manufacturer: MOTOVARIO Variator Type: SF 005 C Application This geared motor assembly is perfectly suited for conveyor systems, mixers, agitators, and other machinery that benefit from adjustable speed and high output torque at low speeds. Country of Origin The main gearbox component is manufactured by NORD Drivesystems in Germany. The motor is from Brook Crompton (UK) and the variator from Motovario (Italy). CO2 Impact Opting for this pre-owned unit prevents the emission of approximately 74.0 kg of CO2, which would have been generated during the manufacturing of a new one. This saving is comparable to the emissions from driving a standard car for 370 kilometers. Availability This item is in stock and available for immediate dispatch.

FAQ How do I adjust the output speed of this unit?The output speed is adjusted manually using the black handwheel on top of the blue Motovario SF 005 C variator. Turning the wheel changes the gear ratio within the variator, which in turn alters the input speed to the main NORD gearbox, thus controlling the final output RPM. What type of oil is required for the different components?The assembly requires specific lubricants for each section. The NORD SK 373.1 gearbox uses ISO VG 220 mineral oil (CLP 220). The Motovario SF 005 C variator requires a specific traction fluid, such as ENI Blasia 32, as indicated on its label. The Brook Crompton motor bearings are typically lubricated for life. Can this geared motor be controlled by a frequency inverter (VFD)?While the Brook Crompton motor itself is inverter-duty capable, using a VFD to control the speed of this specific assembly is not recommended. The mechanical variator is designed to operate with a constant input speed from the motor. Varying the motor’s speed with a VFD could lead to improper operation or damage to the variator’s traction components. The speed should be adjusted mechanically via the handwheel. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
