Warner Electric 5371-169-033 EM Series Electrically Released

SERIES DESCRIPTION

The Warner Electric EM Series (Electro Module) electrically released motor brakes utilize powerful ceramic permanent magnets to provide reliable holding torque when power is removed from the brake coil. Applying a small DC voltage to the coil nullifies the magnetic field and releases the brake, allowing for a springless design that does not limit cycle rates. These prepackaged units automatically compensate for wear, operate with zero lubrication, and are engineered for dynamic stopping and holding applications.

FEATURES

• Fail-Safe Operation: Automatically engages when power fails or is turned off.
• Permanent Magnet Design: Ceramic permanent magnets deliver maximum torque without requiring continuous electrical power.
• Automatic Wear Compensation: Maintenance-free design never needs adjustment throughout its operational lifespan.
• Rugged Housing: Precision cast housing with a vented design built for robust performance.
• UL Listed: Manufactured and certified to industrial compliance and safety standards.

SELECTION PROCEDURE

1. Step 1: Verify Configuration—Select the MBFB style module when planning to mount the unit directly onto the rear of a double-shafted motor.
2. Step 2: Match Frame & Shaft Dimensions—Ensure compatibility by matching the module to the NEMA C-face frame size (213C/182TC or 215C/184TC) and verifying the motor’s rear shaft dimensions line up with the 1.125″ bore requirements.
3. Step 3: Check Dynamic Sizing—Evaluate structural demands against average dynamic torque and thermal parameters to confirm the application cycle rates remain within the designated limits.

HOW TO ORDER

• Specify Part & Model: Order using explicit part number 5371-169-033 for model EM-210-20MBFB (24 VDC).
• Select Compatible Control: Requires a dynamic controller featuring a potentiometer to vary the brake channel output, such as the CBC-160, CBC-300, or CBC-500/550.
