Combination With Gearhead
High-Strength, Low-Noise Gearhead for Increased Torque
Various types of high-strength, low-noise dedicated gearheads are available for brushless motors.
Utilization of the gearhead produces a large torque that cannot be generated by the motor alone, enabling a large-inertia drive.
In addition, the speed fluctuation in response to changes in load can be minimized due to the deceleration effect of the gearheads.

Brushless Motor Features
Structure
Oriental Motor brushless motors are of the inner rotor type.
The rotor is inside the stator, and permanent magnets are placed on its surface. Since the rotor is thin and has a small inertia, it has high responsiveness during acceleration and deceleration.
Also, the stator is located close to the surface of the motor, making it a compact motor with good heat dissipation and high output power.
Power Performance
Torque Curve Has Small Speed Fluctuation
Since the torque design focuses on the practical range from mid to low speeds, it is characterized by low fluctuations in speed relative to load changes.
High-Speed and Low-Speed High-Torque Ranges Can Also be Utilized
In combination with customer-designed drivers, the high-speed range and low-speed, high-torque operating range can also be utilized.
(Limited Duty Region)
Contributes to increased performance of applications.
High Torque Generated per Unit of Current
The large torque constant design allows a small motor to drive a high load.
It can also be used with leeway in areas where torque is capped by current limits due to power supply or circuit constraints.
Reliability and Low Vibration
Low Cogging Torque
Low cogging torque is achieved by using the correct combination of rotor poles and stator slots.
Smooth rotation with reduced vibration and uneven rotation at low speeds.
High Resistance to Eccentric Load
Creep resistance is improved by attaching an O-ring to the bearing’s outer ring. It can be used safely for fan and pump applications.
(Applicable to some round shaft type models where the load is directly attached to the motor’s rotating shaft)
Vibration Suppression Using Rotor Balancing
Rotor imbalance is suppressed by inspection and adjustment. Smooth rotation with reduced vibration and uneven rotation in the mid to high-speed range.
