Permanent Magnet DC Motor
A Permanent Magnet DC Motor is a DC motor with permanent magnet poles. The magnets are radially magnetized and placed on the cylindrical steel stator’s inner sides. This motor does not have a field coil. It generates torque by the interaction of armature flux and permanent flux. Basically, permanent magnets are used to generate the magnetic field required for DC motor operation. These motors offer continuous torques from 0.117 to 3.955 Nm, and peak torques from
0.883 to 24.716 Nm

Shipping & Delivery
- A minimum of 15% handling fee will be levied on goods returned due to no fault of ours if return is made after 7 working days, and if the goods have been correctly processed and delivered provided goods are returned in there original packaging
- Any goods returned will first be subject to a full Technical inspection, should there be any damage to the unit. SAFTRONICS reserves the right to decline the return or charge a larger handling fee.
All prices listed in this online store including shipping costs are purely indicative and are subject to fluctuations based on the prices of our suppliers. Quoted prices may change without notice until we provide you with the final proforma invoice with bank details for payment.
- They are low cost

- Good speed regulation (they are able to maintain a constant speed)
- High efficiency in converting electrical energy to mechanical energy (while running, not during startup)
- Have better heat regulation (i.e. don’t get as hot)
- Simple starting arrangement
- Simple and rugged construction
- Centrifugal pumps
- Industrial drives (e.g. to run conveyor belts)
- Large blowers and fans
- Machine tools
- Lathes and other turning equipment
A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil. One or more windings of insulated wire are wrapped around the core of the motor to concentrate the magnetic field.
The windings of insulated wire are connected to a commutator (a rotary electrical switch), that applies an electrical current to the windings. The commutator allows each armature coil to be energised in turn, creating a steady rotating force (known as torque).
When the coils are turned on and off in sequence, a rotating magnetic field is created that interacts with the differing fields of the stationary magnets in the stator to create torque, which causes it to rotate. These key operating principles of DC motors allow them to convert the electrical energy from direct current into mechanical energy through the rotating movement, which can then be used for the propulsion of objects.
While the principles are the same across variants, there are actually several different types of DC motors, which offer specific advantages and disadvantages over each other. See product description below for more information.
