PG28BL28 series Gearmotors consist of 28mm planetary gearboxes and 28mm BLDC motors.
The planetary gear motors are equipped with a hall sensor type brushless DC motor to increase the torque and lower the output speed to meet your application or project demands.Twirl offers rushless DC Gearmotors with hall only feedback or with a control board that is fully integrated to the internal motor.When mated to our planetary gearbox, this brushless gearmotor offers extremely long life and high torque in a compact size.
Benefits of the brushless motor
DC motors with no brushes mean no mechanical contact, no dust and no sparks.There are no motor brushes to wear out because the windings are electrically commutated.Exquisitely efficient small form factor BLDC motor that has peak operating efficiency . High torque from a small form factor, with low power consumption and peak performance at lower RPM for quiet operation.
Speed and direction is controlled easily and accurately, offering you a full range of options with every motor.
The Brushless Motors offers distinct advantages over the competition: exceptionally long service life (over 20000 operating hours), very low sound level (no brushed switching), good efficiency (optimized motor control), integrated sensors and excellent dynamics.
This motor features built-in controls,versatile and very simple to use.
Why do we use BLDC motors?
In manufacturing, brushless motors are primarily used for motion control, positioning or actuation systems. Brushless motors are ideally suited for manufacturing applications because of their high power density, good speed-torque characteristics, high efficiency, wide speed ranges and low maintenance.

How to calculate the output data of the geared motor?
1:Output no load speed=Motor no load speed /reduction ratio
2:Output rated load speed=Motor rated speed /reduction ratio
3.Output rated load torque= motor rated torque X reduction ratio X gearbox efficiency
Bushless motor Connection
How to operate the brushless wires?
This motor features built-in controls,versatile and very simple to use.
1) Red wire(+) of the controller is connected to +12VDC, and balck wire (- )to GND.
2)The green linkes the PWM
3)When the white wire is shut off ,the motor runs at full speed with CW
4)The motor stops running when the white wire is connected to black wire.
5)When the yellow wire was connected to black one, the motor runs with CCW
6)The blue wire can be detected by OSC means speed signal output
7)When the green linkes the black,motor is running
