Overview
The Transtecno ND series is a compact range of rare earth DC electric motors designed for applications that need strong torque from a small motor body. These motors use neodymium NdFeB permanent magnets, which provide high magnetic energy and allow the motor to produce higher torque values in reduced dimensions.
For Australian machinery builders, equipment manufacturers and maintenance teams, this makes the ND series a practical option when space is limited but torque demand remains high. The range is available with low voltage 12 Vdc and 24 Vdc supply options, making it suitable for battery powered systems, mobile equipment and compact DC drive assemblies.
The ND range is available in a 65 mm diameter tubular construction without fan, with 160 W S2 and 250 W S2 power options. Compared with standard permanent magnet DC motors of similar size, the neodymium magnet design allows higher torque and higher power output in a compact package.
Key Features
The main advantage of the ND series is its rare earth magnet design. Neodymium magnets have high resistance to demagnetisation and a high magnetic saturation value, which allows the motor to store a large amount of magnetic energy. In practical terms, this helps deliver high starting torque and strong performance from a compact DC motor frame.
Key features include:
- Neodymium NdFeB permanent magnet construction
- Compact 65 mm motor diameter
- Tubular body without fan
- 12 Vdc and 24 Vdc low voltage supply options
- 160 W S2 and 250 W S2 power ratings
- 120 W S1 and 180 W S1 continuous power ratings
- High starting torque
- Ball bearing supports
- 8 mounting holes
- 4 graphite and copper composite brushes
- Standard rear shaft
- 1000 mm electric cable
- Suitable for encoder or brake assembly
This combination makes the ND series well suited to compact drive systems where a standard DC motor may not provide enough torque within the available space.
Common Applications
ND series rare earth DC electric motors are often used where low voltage supply, compact motor dimensions and high starting torque are important. The range is suited to equipment that needs responsive DC motor performance without moving to a larger motor frame.
Common application areas include:
- Battery powered industrial equipment
- Mobile machinery and compact drive systems
- Low voltage automation equipment
- DC gearmotor assemblies
- Actuation systems
- Small conveyors and handling systems
- OEM machinery where space is restricted
- Equipment requiring brake or encoder compatibility
For Australian businesses, these motors can be useful in both new machinery builds and replacement motor projects where the existing design has strict space, voltage or torque requirements.
Available ND Series Configurations
The ND series includes 12 Vdc and 24 Vdc models across two main power levels.
ND120 Models
The ND120 range is available in 12 Vdc and 24 Vdc versions.
Confirmed specifications include:
- 160 W S2 20 minute rating
- 120 W S1 continuous rating

ND180 Models
The ND180 range is also available in 12 Vdc and 24 Vdc versions.
Confirmed specifications include:
- 250 W S2 20 minute rating
- 180 W S1 continuous rating
- 0.80 Nm rated torque in S2 operation
- 0.57 Nm rated torque in S1 operation
- 3000 min-1 rated speed
- IP20 protection class
- 1.95 kg weight
- Insulation class F
The correct model will depend on the required voltage, torque, duty cycle and operating conditions of the application.
Brake And Encoder Options
The ND series is suitable for brake and encoder assembly, which can be important for applications requiring controlled stopping, holding, feedback or positioning.
Brake options include:
- ND brake configuration
- ND brake with hand release configuration
- 12 V or 24 V brake voltage
- 1.8 Nm brake torque
- 3000 min-1 brake speed rating
Encoder options include a 2 channel encoder with 5 Vdc TTL power supply and available CPR resolutions including 1, 100 and 300. For non standard encoder resolution requirements, the correct option should be confirmed during selection.
Selection Considerations
Selecting the correct ND series DC motor should be based on more than motor power alone. DC motor performance is strongly affected by load, torque demand, duty cycle and supply type.
Important selection factors include:
- Required supply voltage, either 12 Vdc or 24 Vdc
- Required output torque
- Starting torque demand
- Duty cycle, including S1 continuous or S2 short time operation
- Available mounting space
- Whether a brake is required
- Whether encoder feedback is required
- Expected operating load and current draw
- Gearbox or gearmotor pairing requirements
Because motor speed and absorbed current change with applied torque, it is important to match the motor to the real operating load rather than selecting by wattage only. This helps avoid undersizing, overheating or poor performance in the final equipment.
