Metalrota: Direct Current Motors (DC Motors)
Metalrota DC MOTORS
Metalrota DC motors are mostly designed for traction
applications. In this case, the motor works intensively and needs great
flexibility, in order to guarantee a huge number of high torques during the
starting and acceleration processes and get optimum performance at high speed.
According to the application, we can supply different
types of windings:
– Permanent magnets (for light and cheap applications)
– Four terminals separately excited (the most common one related to the
electric traction system)
– Four terminals shunt excitation with constant alimentation of the stator (for
AGV applications)
– Four terminals series excitation (not widely used in electric traction, but
easier in terms of prototyping and able to supply high stall torques)
– Two terminals series/compound/shunt excitation for applications with gear
pumps.
Class F motor insulation is possible thanks to a class
H Superior insulation wire that has a thermal resistance of 210°C. Furthermore,
the rotor is treated with epoxy paints and resins that higher firmness and
resistance up to 155°C.
According to the motor type, graphite electro or
graphite metal brushes are available and easily accessible during the
maintenance operations.
Brush holders are characterized by four metal sides brush boxes that assure
contact perpendicularity between brushes and commutator.
Double shielded ball bearings are characterized by an
internal lubrication and delivered by important suppliers such as NSK and NTN.
These high-quality components have been selected in order to assure the use
flexibility needed by an electric motor. Thanks to them, motors designed for
short term service can satisfy heavy load applications (e.g. lifting).
Our DC motors are specifically designed for battery
operated vehicles:– From 12V up to 96V
– From 300W up to 15kW of nominal power
– Electromagnetic brake: Metalrota motors may be equipped with electromagnetic
brakes from 5Nm up to 100Nm, possibly with a protection grade of IP65
– Motors can be supplied with a protection grade from IP20 up to IP54
Our products are manufactured complying with IEC and European standards.
– Vibration degree (EN 60034-14 IEC 60034-14): motor vibrations are completely
eliminated thanks to the précised balancing of the Standard rotor DIN ISO 8821
up to the nominal speed.
– Our products are manufactured complying the EN 60034, IEC 60034 standards and
the REACH 81907/2009/CE, RoHS (95/2002/CE + 65/2011/CE) environmental
protection regulations.
The following optional are available on demand:
– Thermal protections and wear detectors
– Incremental/absolute encoders
– Tacho generators
– Contactors
The most common motors data can be found in the
catalogue. Standard flanges are usually manufactured according to B14 and B5
IEC norms but, on request, we are able to produce different types of motors:
– Splined shafts, special and custom flanges, foot mountings
– Voltage, power and rpm are selected according to the application
Electric motors in Direct Current with different types of windings:
Permanent magnets (for light applications), separately excited (for the
electric traction system), shunt excitation with constant alimentation of
the stator (for AGV applications), series excitation (to supply high stall
torques), series/compound/shunt excitation for applications with
gear pumps.
