Groschopp Introduces An Updated Brushless DC Motor

March 21, 2013 By MCTips Staff Leave a Comment

Groschopp Inc. introduces an updated Brushless DC (BLDC) motor and several gearmotor combinations. Due to the lack of wear components, the BLDC motor is considered to be a maintenance-free, high reliability motor with a life of 20,000 hours or more. Typically only the bearings will limit a brushless motor’s life. With an outside square dimension of 73.3 mm (2.88 in) to 90.2 mm (3.55 in) the brushless motor is available in two sizes and a variety of voltages, 12, 24 and 163VDC/115VAC, offering broad torque and speed ranges.

Characteristics:

  • Variable speed or torque operation
  • High efficiency between 65% – 85%
  • High starting torque
  • 20,000+ hours life
  • No maintenance
  • High power density
  • Totally enclosed, non-ventilated
  • Continuous rated speeds 2,600 to 3,800 rpm
  • Continuous rated torque of 1.8 to 10.8 in-lb

Groschopp catalog combinations include: right angle worm, planetary, parallel shaft, and right angle planetary reducers. The gearmotor combinations are tested and optimized using a custom interface designed to ensure the motors and gearboxes function flawlessly as one unit. The interface eliminates the need to purchase a motor and gearbox separately, eliminating design and assembly time.

Similar in performance to a Permanent Magnet brush-type motor, the speed of a brushless DC motor is proportional to the voltage supplied and the torque is proportional to the current supplied, but a BLDC motor does not require brush replacement of a typical PMDC motor. Compared to AC Induction motors, BLDC motors possess a higher starting/stall torque and more horsepower in a comparable frame size. Generally, a smaller motor can be specified due to high efficiencies and the increased power density of the BLDC motor, allowing a robust motor to be integrated in a small area.

The BLDC motor is designed using standard 120° Hall Effect switches; a control is required for the BLDC motor to commutate. With the use of a proper control the motor can achieve highly customized performance characteristics. Optional feedback devices are available including incremental and absolute encoders.
