They produce more output power per frame size than AC or permanent magnet DC motors and gearmotors. Low rotor inertia improves acceleration and deceleration times while shortening operating cycles, and their linear speed\/torque characteristics produce predictable speed regulation. With brushless DC motors, brush inspection is eliminated, making them ideal for limited access areas and applications where servicing is difficult or not desired. Low voltage models are ideal for battery operation portable equipment, or medical applications where shock hazards cannot be tolerated.<\/p>\n<p><a href=\"https:\/\/www.bodine-electric.com\/blog\/\/wp-content\/uploads\/2015\/07\/bldc-gearmotors-bodine-benefits-features_07-2015blog1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2205 size-large alignnone\" src=\"https:\/\/www.bodine-electric.com\/blog\/\/wp-content\/uploads\/2015\/07\/bldc-gearmotors-bodine-benefits-features_07-2015blog1.jpg?w=500\" alt=\"BLDC-Gearmotors-Bodine-Benefits-Features_07-2015blog\" width=\"500\" height=\"320\" srcset=\"https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bldc-gearmotors-bodine-benefits-features_07-2015blog1.jpg 646w, https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bldc-gearmotors-bodine-benefits-features_07-2015blog1-300x192.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p><strong>A<\/strong><strong>pplications and Industries:<\/strong><\/p>\n<ul>\n<li><strong>Laboratory equipment<\/strong> where quiet, clean, long-life operation is critical such as blood analyzers, centrifuges, mixers, shakers, MRI or cat scan equipment<\/li>\n<li><strong>Packaging equipment<\/strong> for labeling, bottling, glue applicators, shrink tunnels<\/li>\n<li><strong>Factory automation<\/strong> and conveyor systems<\/li>\n<li><strong>Photocopiers, printers,<\/strong> and printing presses<\/li>\n<li><strong>Pallet feeders<\/strong> for plastic processing<\/li>\n<li><strong>Metering pumps<\/strong> for chemical treatment, lab equipment, and industrial processes<\/li>\n<li><strong>Solar power,<\/strong> alternative energy sources, remote locations<\/li>\n<li><strong>Food processing,<\/strong> food handling, commercial ovens<\/li>\n<li><strong>Automated barriers,<\/strong> parking lot gates, door openers<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.bodine-electric.com\/blog\/\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-bldc-blog-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2194 alignnone\" src=\"https:\/\/www.bodine-electric.com\/blog\/\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-bldc-blog-1.jpg\" alt=\"Bodine-Gearmotor-BLDC-Blog-1\" width=\"500\" height=\"111\" srcset=\"https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-bldc-blog-1.jpg 891w, https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-bldc-blog-1-300x66.jpg 300w, https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-bldc-blog-1-768x170.jpg 768w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p><strong>Frequently Asked Brushless DC Motor and Gearmotor Questions:<\/strong><\/p>\n<p><strong>Q:<\/strong> Can I make my own extension cable?

Lower when used with a servo amplifier.<\/p>\n<p><strong>Q:<\/strong> What should I check first if a brushless DC motor stops working?<br \/>\n<strong>A:<\/strong> Check set-up, wire harness and connections.<\/p>\n<p><strong>Q:<\/strong> My red fault light is on!<br \/>\n<strong>A:<\/strong> Noise might be coming into the input of the control or there might be overvoltage to control input.<\/p>\n<p><strong>Q:<\/strong> Can I have preset fixed speed settings?<br \/>\n<strong>A:<\/strong> Yes, replace the pot with a resistor divider with rotary switch. Or control the analog voltage signal to the speed pot input via a PLC or other controller.<\/p>\n<p><strong>Q:<\/strong> Can we run faster than 2500 RPM?<br \/>\n<strong>A:<\/strong> Yes, by adjusting the MIN\/MAX pot &#8211; However, the available speed range will change.<\/p>\n<p><a href=\"https:\/\/www.bodine-electric.com\/blog\/\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-comparison-of-variable-speed-systems.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" size-full wp-image-2190 alignnone\" src=\"https:\/\/www.bodine-electric.com\/blog\/\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-comparison-of-variable-speed-systems.jpg\" alt=\"Bodine Gearmotor Comparison of Variable Speed Systems\" width=\"500\" height=\"234\" srcset=\"https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-comparison-of-variable-speed-systems.jpg 887w, https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-comparison-of-variable-speed-systems-300x141.jpg 300w, https:\/\/www.bodine-electric.com\/blog\/wp-content\/uploads\/2015\/07\/bodine-gearmotor-comparison-of-variable-speed-systems-768x360.jpg 768w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p><strong>We Offer a Large Selection of Standard Products:<\/strong><\/p>\n<ul>\n<li>Matched gearmotor-control system solutions<\/li>\n<li>12, 24, and 130 VDC motors, gearmotors, and controls<\/li>\n<li>High speed (up to 20,000 RPM) motors and controls<\/li>\n<li>Two-year limited warranty for matched Bodine motor-control systems<\/li>\n<li>22B\/SR and 34B\/FV 24VDC INTEGRAmotors&#x2122; provide integrated motor, control and feedback systems<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>And when a Standard Product won&#8217;t fit &#8211; Custom Solutions from Bodine:<br \/>\n<\/strong><\/p>\n<ul>\n<li>48B motor achieves up to 1.5 HP with matched speed control (type EBL)<\/li>\n<li>Analog (SR) and Digital (FV) interface INTEGRAmotor options<\/li>\n<li>Environmentally protected versions for OEM applications<\/li>\n<li>Third-party markings, including Class I\/Div 2<\/li>\n<li>Custom control designs available for OEM applications<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><strong>To download a PDF version of this blog post, please <a href=\"https:\/\/www.bodine-electric.com\/core\/files\/bodineelectric\/uploads\/files\/bodine_bldc_technical_overview.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">click here<\/a><\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<p class=\"smallheading\"><strong>Learn More:<\/strong><\/p>\n<p><a href=\"http:\/\/www.bodine-electric.com\/Asp\/ProductGroup.asp?Context=15\"><span style=\"color: #0000ff;\">Brushless DC Motors &gt;&gt;<\/span><\/a> <a href=\"http:\/\/www.bodine-electric.com\/Asp\/ProductGroup.asp?Context=16\"><span style=\"color: #0000ff;\">Brushless DC Parallel Shaft Gearmotors &gt;&gt;<\/span><\/a> <a href=\"http:\/\/www.bodine-electric.com\/Asp\/ProductGroup.asp?Context=17\"><span style=\"color: #0000ff;\">Brushless DC Right Angle Gearmotors &gt;&gt;<\/span><\/a> <a href=\"http:\/\/www.bodine-electric.com\/Asp\/ProductGroup.asp?Context=21\"><span style=\"color: #0000ff;\">12 &amp; 24VDC ABL (Brushless DC Speed Controls) &gt;&gt;<\/span><\/a> <a href=\"http:\/\/www.bodine-electric.com\/CustomSolutions\/\"><span style=\"color: #0000ff;\">Custom Class I, Div 2 Brushless DC Gearmotors &gt;&gt;<\/span><\/a> <a href=\"http:\/\/www.bodine-electric.com\/Asp\/ProductGroup.asp?Context=18\"><span style=\"color: #0000ff;\">INTEGRAmotor integrated motor\/control\/feedback device &gt;&gt;<\/span><\/a><\/p>\n<p style=\"text-align: center;\">Copyright <a title=\"Bodine Electric Home Page\" href=\"http:\/\/www.bodine-electric.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">Bodine Electric Company<\/a> \u00a9 08\/2015.
