Bodine 24A and 42A Motors Successfully Pass UL’s IP-66 Test

Bodine IP-Ratings-UL-Test_per IEC-529 Bodine Electric GearmotorsOEM applications often require gearmotors and motors that exceed the design features of our standard products. But with over 110 years of design and application engineering experience with FHP motors and gearmotors, we can add and include special design features and modifications for those demanding OEM applications.

One such example is our recent approval by Underwriters Laboratory (UL) to mark and manufacture PMDC motors that meet IP-66 environmental protection requirements.

02-Bodine-MotorIP-66-UL-Test_42A1This UL approval is based on a specific set of modifications that each frame size must contain in order to comply with IP-66. In most cases, the design features include O-rings, liquid tight connectors, and sealing washers. We can also add design features such as stainless steel hardware and stainless steel motor and drive shafts. These types of modifications are available as custom features for most of our gearmotor and motor designs.

Bodine-Motor-IP-66-UL-Vacuum-Poweder-Test_24AThe IP rating matrix per IEC 60034-5 (and IEC-529) details a level of dust and water ingress permitted within the product, and its post-test functionality (see below table). Our IP-66 designs and ratings guarantees ZERO ingress of dust into the motor housing under a vacuum (negative pressure), and ZERO ingress of water from a high pressure water hose.

With the above mentioned design features incorporated into select PMDC products, the motors will be well suited for demanding applications, and ultimately guarantee the desired performance for the design life of the product. The features were designed to be as economical as possible, designed for “manufacturability”, and without major modifications to the exterior of the motors.

This video provides answers to questions like: What is a gearmotor? Why use FHP gearmotors? We talk about some of their main features and benefits, and we review the most common gearing and gearhead styles: parallel shaft, right angle, and planetary (center shaft) gearmotors. Tom closes with a brief review of the available types of motors that are commonly used: AC induction, permanent magnet DC, brushless DC.

New 34B/SR-WX Brushless DC Gearmotors – 12/24VDC, CI/D2

New Brushless DC Gearmotors with Control – 12/24VDC, CI/D2, type 34B4/SR-WX

These new 34B/SR-WX, brushless DC, 12 or 24VDC, INTEGRAmotor gearmotors are ideal for low-voltage applications in remote locations that operate off-grid, from battery or solar power. These new gearmotors are also suitable for a wide range of industrial or medical applications that only allow low-voltage electronics due to user-safety considerations.

Bodine Brushless DC Gearmotor with control 12/24VDC, meets C1D2

The gearmotors feature a built-in speed control with speed pot, and are IP-44 with proper conduit installed. These new standard products are also UL listed for operation in hazardous locations per NEC, Class I, Div 2 environments (Groups A, B, C or D). Minimum order quantities and lead-times apply. Please contact your regional Bodine sales manager for assistance with samples and with further questions.

Connection Instructions for 34B/SR-WX Gearmotors in Non-Hazardous Locations Bodine App-Note_34B-SR-WX_non-haz-remote-wiring

This application note explains the steps to properly wire these new, standard 34B/SR-WX, 12/24VDC gearmotors for remote operation in a non-hazardous location. Click here to download the PDF. For remote operation of these products in Class I/Div 2 environments, please refer to all local safety rules and regulations. Contact our tech support team at 773-478-3515 or via info@bodine-electric.com, if you require further assistance.

User Manual, Sell Sheet, Product Specifications and 2D/3D CAD Drawings are Available Online

Brushless DC Gearmotor Overview – Features and Benefits

Brushless DC (EC) Gearmotors and Motors – What Is a Brushless DC Motor?

Brushless DC motors could be called “inside-out permanent magnet motors” because brushless DC motors have their magnets on the rotating part of the motor instead of on the stationary part. Accordingly, they have their windings on the stationary part of the motor instead of on the rotating part, as in a permanent magnet DC motor. Despite the differences in construction, their speed-torque curves are very similar to those of permanent magnet DC motors.

BLDC Gearmotors Bodine Products 08/2015

Operation of a brushless DC motor is similar to a permanent magnet motor except that the winding phases are switched on and off electronically by means of a control device. That is why we also refer to these motors as Electronically Commutated (EC). The control “knows” when to switch the windings because of feedback it receives from rotor position Hall effect sensors.

Brushless DC Advantages Bodine-Gearmotor-BLDC-Blog-4

Brushless DC motors require less maintenance, provide long life, low EMI, and quiet operation. 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.

Frequently Asked Brushless DC Motor and Gearmotor Questions:

Q: Can I make my own extension cable? What do I have to consider?
A: Yes, you can make your own cable, however they must have EMI and RFI shielding. Most wiring errors are due to improper or missing shielding.

Q: How long can the cable be?
A: 50 Feet maximum

Q: What is the minimum speed of Bodine brushless DC stock motors?
A: 150-200 RPM, depending on what kind of control is being used. Lower when used with a servo amplifier.

Q: What should I check first if a brushless DC motor stops working?
A: Check set-up, wire harness and connections.

Q: My red fault light is on!
A: Noise might be coming into the input of the control or there might be overvoltage to control input.

Q: Can I have preset fixed speed settings?
A: 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.

Q: Can we run faster than 2500 RPM?
A: Yes, by adjusting the MIN/MAX pot – However, the available speed range will change.
