The new Hydromec range of helical geared motors can deliver significant cost savings in light to medium duty applications such as conveyors, feeders, pumps, mixers and food processing machinery.
The new Hydromec range of helical geared motors from Lenze can deliver significant cost savings in light to medium duty applications such as conveyors, feeders, pumps, mixers and food processing machinery.
Covering powers from 90W to 4.0kW, the Hydromec geared motors offer advantages from the aluminium casing design, plus lubrication for life and ATEX compliance.
The aluminium alloy gear housings mean less machining and lower purchase costs.
As well as offering a cosmetic match to aluminium framed motors, the gearbox housings do not require painting, which means a small cost saving for many applications.
Problems with oil leakage are avoided through vacuum impregnation of the casings.
An additional advantage of the aluminium design is weight reduction.
The modularity of the Hydromec range with the options to bolt flanges and feet to the gear housing results in short delivery times for a wide range of models, and customers benefit from only paying for the parts they need.
Bolt on input flanges can be to IEC or NEMA specification, and together with shaft reducers permit two or three motor frame sizes to be fitted to a single gearbox housing.
Bolt on output flanges are available, but customers can opt for face mounting without flanges to further reduce costs.
The bolt on feet are available in configurations to match the dimensions of nine other geared motor ranges on the market, so making spares replacements an easy decision.
The Hydromec range covers motor powers from 90W to 4kW, mostly with four-pole motors, and typical output speeds are 23-250rev/min.
A full range of speeds from 11 to 1800rev/min is also possible.
Gearboxes are available in five sizes and with one-, two- or three-stage designs.
The ability to achieve a ratio of 61 in two-stage gearboxes will save money from some customers, and for larger ratios, the three stage version is compact and also cost attractive.
Output torques range from 30 to 460Nm.
Hydromec geared motors are well suited to inverter variable speed control.
The low cost and simple Lenze smd inverter is an ideal partner.
The variable speed range can be optimised by increasing the full speed setting up to 70Hz, representing about 2000rev/min.
This means a speed range of more than 3:1 and continuous rated duty can be achieved without the cost of adding a force ventilation blower.
Hydromech is sold and supported by Lenze group in Europe and a 2-year warranty is offered.
Gearboxes are lubricated for life with synthetic oil.
A further advantage is the possibility to achieve ATEX standards for a minimal surcharge.
Both ATEX Category 3 and Category 2 are offered.
