What determines the life expectancy of a Brushed DC motor? Typically, the brushes are the limiting component in a Brush DC motor's life expectancy. The life expectancy of the brush is dependent on application parameters such as torque, speed, duty cycle and |
What is a brushless motor? A Brushless DC (BLDC) motor is a rotating electric machine where the stator is a classic three-phase stator like that of an induction motor and the rotor has surface-mounted permanent magnets. In thi |
Are there any noise benefits of a Brushless motor? Yes, with the elimination of brushes, BLDC motors can be regulated to slower operating speeds without sacrificing torque. Brushless motors can also utilize skewed magnets to reduce the effect of cogg |
What determines the life expectancy of a Brushless motor? The life expectations of a BLDC motor are dependent on the operating conditions and environment. Under “ideal” conditions, a BLDC motor-only will have minimal wear and will have a long life span. |
What are the advantages of using a brushless motor versus a brush style motor? No brush noise, efficient, durable, robust, easy to cool Linear current/torque Synchronous speed control Position and Speed Servo (open/closed loop) Customizable Performance Extended Life |
How do I control speed and keep it constant? A sophisticated control system would be required to keep the speed regulated to a tight tolerance. Utilizing an encoder feedback, the customer’s control can monitor and adjust the 0-5VDC input can |
How can I calculate my power needs? A simple formula can be used to roughly determine what is needed power-wise. Here’s an example:
Motor Speed:
3600 RPM
Motor Torque:
340 mNm = 48 inoz = 3
|
What environmental considerations are there? Typical environmental temps for the motor should be run in a low humidity environment with an ambient temperature range of –20 C to +50 C. BLDC motors do have IP ratings associated to them and limi |
Are two power sources needed for integral control motors? Motors can be programmed to function with only one power source. This scheme would be a setup where on/off is the only requirement. Typically, motors that will speed regulate, will require two power |
What is the voltage range of the Brushless products? The integral control option for the 2.25” has a standard input voltage range of 12-48 VDC. If an external controller is used, customer’s controller will determine the voltage range of the motor. |
