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.

  BLHM230K-A(□60 mm-30 W)

  Driver Power Wupply Voltage: 24 VDC

  

• 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.

  BLM030DHK-A(□42 mm-30 W)

  Driver Power Wupply Voltage: 24 VDC

  

• 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. (Only round shaft^* connector type). It can be used safely for fan and pump applications.

  • *Round shaft is a type that the load could directly attached to the motor 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.
