24V 48V Low Speed High Torque DC Motor DC Planetary Gear Motor High Torque DC Motor with Planetary Gearbox Gear Ratio: 1: 36

 A DC Motor whose poles are made of Permanent Magnets is known as Permanent Magnet DC (PMDC) Motor. The magnets are radially magnetized and are mounted on the inner periphery of the cylindrical steel stator. The stator of the motor serves as  a return path for the magnetic flux. The rotor has a DC armature, with commutator segments and brushes.

Applications of the Permanent Magnet DC Motor

The PMDC motors are used in various applications ranging from fractions to several horsepower.  They are developed up to about 200 kW for use in various industries. The following applications are given below.

PMDC motors are mainly used in automobiles to operate windshield wipers and washers, to raise the lower windows, to drive blowers for heaters and air conditioners etc.

They are also used in computer drives.high torque dc planetary gear motor

These types of motors are also used in toy industries.

PMDC motors are used in electric toothbrushes, portable vacuum cleaners, food mixers.dc high torque geared motor

Used in a portable electric tool such as drilling machines, hedge trimmers etc.

Advantages of the Permanent Magnet DC Motor

Following are the advantages of the PMDC Motor.

They are smaller in size.24v dc motor low rpm

For smaller rating Permanent Magnet reduces the manufacturing cost and thus PMDC motor are cheaper.

As these motors do not require field windings, they do not have field circuit copper losses. This increases their efficiency.
