Introduction to Brushless DC (EC) Motor and Gearmotor Technology
Brushless DC Gearmotors and Motors In Section 3.1 of the Bodine Electric Handbook we discuss how motor action is achieved in a conventional permanent magnet DC (PMDC) motor. A segmented commutator rotating within a stationary magnetic field causes mechanical switching of the armature current. In a brushless DC (BLDC) gearmotor or motor, the magnetic fieldVIEW
Advantages and Disadvantages of Planetary Gearmotors
We design all our standard parallel shaft (helical or helical/spur) and right angle (worm or helical/worm) gearboxes in-house, and all gearheads are manufactured and assembled in our main factory in Iowa. Occasionally, we’ll receive a request to mate one of our standard AC, DC or BLDC motors to a planetary gearhead. To identify the best gearmotor option for our customer’sVIEW
New High-Torque PMDC Gearmotors 12/24V or 90/130 VDC
The new 42A5-FX is a completely redesigned permanent magnet DC (PMDC) parallel shaft gearmotor that provides up to 40% more torque than previous E/F models. Forty (40) new stock models are offered with either 12/24VDC or 90/130 VDC rated motor windings. New synthetic lubricant allows the FX gearhead to operate at a wider temperature rangeVIEW
Permanent Magnet (PM) DC Gearmotors and Motors
Features and Benefits of PMDC Gearmotors and Motors: Continuous duty operation DC power supply (battery or speed controls – 12/24V, 90/130V, 180V) Reversibility at rest or during rotation with current limiting Relatively constant and adjustable speed Starting torque 175% and up of rated torque High starting current, relative to full load running current Design andVIEW
Bodine Electric Company’s Quality Management System Now Certified to ISO 9001:2008
Bodine Electric Company attained ISO 9001:2008 certification for our Northfield (Chicago area) and Peosta, Iowa locations. This ISO 9001:2008 certification is the latest milestone in our long-term commitment to continuous improvement and meeting the requirements of the most demanding customer applications. ISO 9001:2008 certification of our quality management system covers all aspects of the company’sVIEW
Selecting DC Motor Speed Controls for PMDC Gearmotors
Basic DC motor speed controls accomplish the conversion of AC power to DC with varying degrees of DC voltage “purity.” For proper control selection you’ll need to identify which performance criteria are important to your application. We’ll review how different speed controls affect the quality of DC output and consequently, the performance of your DCVIEW
New 34B/FV-F INTEGRAmotor BLDC stock gearmotors
We just added a new series of 24V brushless DC (ECM) gearmotors to our standard INTEGRAmotor™ product line. The new type 34B4/FV-F gearmotors combine a PWM speed control, a brushless DC motor, a high-torque gearhead, and an optical encoder into one high-performance drive package. The 34B/FV-F gearmotors provide 1/4 hp (187 watts) and up to 341 lb-in. (39 Nm)VIEW
Low-Voltage DC Motor Speed Controls (12 & 24V) for PMDC Gearmotors and Motors
Bodine Electric Company developed four new stock models to provide simple and reliable speed control for low-voltage 12 or 24V PMDC gearmotor and motor applications (up to 1/3 HP / 250 Watts). The controls utilize pulse width modulation (PWM) technology to insure quiet operation, low operating temperature and optimal brush life. The controls feature five trim pots toVIEW
Design Tips for Gearmotor Applications
To select the best gearmotor for an application, one must go into more detail than just selecting the best suitable output speed and torque. Here are five criteria you should consider. 1. Gearmotor Mounting Orientation Gearmotors are typically designed to be mounted with the gearbox level with the motor, and with the drive shaft inVIEW
