Bodine Electric introduces Permanent Magnet DC Motors & Gearmotors

Bodine Electric Co. (www.bodine-electric.com) is proud to announce the latest brush-wear monitoring system developed for its popular line of 42-frame permanent magnet DC (PMDC) motors and gearmotors. The OEM versions of the type 42A products are equipped with built-in electronic brush-wear sensors, which are fully integrated into the motor housing. These special sensors signal when one of the brushes is nearing the end of its useful life.

The unique sensor system permits OEMs to monitor brush wear electronically in order to maintain uninterrupted operation of the PMDC motors or gearmotors. It also removes the guesswork in brush inspection and maintenance. Motors and gearmotors that are equipped with this feature can accommodate built-in EMI filtering and built-in magnetic encoder. The company is already in the process of searching for patent protection for this latest technology. PMDC gearmotors and motors that feature the proprietary design are exclusively available from Bodine Electric Company.

“This is the sort of value-added and innovative design engineering that sets Bodine apart. One of our customers approached us with the challenge of monitoring brush-wear and motor life in a battery- and solar-powered application. We took care of the motor solution with this new technology, and the customer integrated the sensor feedback into his control system,” said Terry Auchstetter Manager of Custom Solutions and Business Development of Bodine Electric.

The sensor system is best suited for remote monitoring of PMDC motors or gearmotors, especially when nobody is standing next to a machine all day.

RE50 Brushed DC Motor from maxon

Maxon’s RE 50′s “heart” is, as with all mechanically commutated maxon motor drives, the ironless rotor, which results in detent-free running and minimized mass inertia. The combination of a two-pole Neodymium permanent magnet with the patented maxon winding technology results in high torque and remarkable acceleration.

The drive measures Ø50 x 108 mm and is available with four different windings. It reaches a nominal torque of up to 0.38 Nm, a nominal speed of 2800 to 5700 rpm and an efficiency of more than 90%. Low nominal voltage (24.70 VDC) and high power density make the RE 50 an excellent choice for the use in battery-powered applications, such as electric vehicles, transport and logistics equipment, mobile systems, robots, etc.

Pre-loaded bearings contribute to low-vibration and quieter running and an extensive life span. The well proven maxon modular system offers matching planetary gearheads, encoders and control systems. Look for more information soon on a dust and splash water protected RE 50 version, which will be available with an optional brake.

Lin Engineering NEMA 23 Brushless DC Motors

Santa Clara, CA — Lin Engineering announces the release of their new line of NEMA 23 Brushless DC (BLDC) motors.  These motors are best for applications where high speed and high dynamic torque are a must for the user’s application.

Lin’s NEMA 23 BLDC’s provide extremely quiet and smooth operation regardless of speed range, although the optimal performance speed range is 300RPM to 4000RPM.  These are also great for those who prefer velocity control with an analog input, do not need holding torque and may be having reliability issues with an existing Brush DC motor.  BLDC’s are also a good choice for applications that do not have a lot of power and require a higher efficiency motor.

Lin Engineering’s NEMA 23 BLDC’s are available in four stack lengths: 2.00”, 2.80”, 3.60”, and 4.53”.  Depending upon the stack length, these motors are able to produce up to 190 oz-in of peak torque.
