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
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
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
Measuring Armature Circuit Resistance in a PMDC Motor
Application Notes & Gearmotor Tips: When a permanent magnet DC (PMDC) motor fails to operate properly, or fails to run at all, one sensible troubleshooting step is to measure the winding resistance to determine if there’s an open circuit or a short circuit, either between turns of the same winding, between two windings in theVIEW
High-Performance Type “48B” Brushless DC (ECM) Motors and Gearmotors
Type 48B Brushless DC Motors and Gearmotors from Bodine The new special-order 48B is twice as powerful as previous BLDC motors from Bodine. Delivering up to 1.5 HP (1100 Watts) output at 260VDC (3000RPM), it brings all the benefits of brushless DC technology to applications that in the past might have required higher-cost servo motors.VIEW
What is a Sensorless Brushless DC Control? How does it work?
A sensorless brushless DC control consists of a power supply, a power stage, commutation logic, and startup logic. The key difference to an electronically commutated BLDC motor system is that the Hall sensor inputs are replaced by a system that measures generated voltage (BEMF = back EMF) and uses zero crossings to determine when toVIEW
Application Tips: Troubleshooting a Brushless DC (ECM) Motor and Control System
One of our authorized distributors called our Tech Support staff in Chicago recently because his customer was having problems with a Bodine 34B4BEBL brushless DC motor and our ABL-3911 control. Our products were designed into a new machine that is used to induction-harden steel shafts. 1) Because of the distance between the motor and the control, theVIEW
