SERIES DESCRIPTION
The Warner Electric EM Series (Electro Module) motor brake modules are individual electromagnetic units designed for direct mounting to C-face motors. The 20MB motor brake features an integrated end cap and does not include an output shaft, providing compact stopping and holding capability directly on the motor. They are easy to install, maintenance-free, and require no lifetime lubrication.
FEATURES
- Modular Flexibility: Bolts directly to NEMA C-face motors with an integrated end-cap design.
- Shaftless Motor Brake: Designed specifically for motor-mounted braking without an extension shaft.
- Fast & Consistent Cycling: Designed for rapid cycle rates and smooth engagement in dynamic applications.
- Maintenance-Free: Self-adjusting design requires no lubrication or life-cycle adjustments.
- Rotatable Conduit Box: Integrated mounting bolts allow top or side positioning for wiring convenience.
SELECTION PROCEDURE
- Step 1: Match NEMA Frame Size—Select module size based on prime mover requirements (Size 50 fits 56C/48Y frames).
- Step 2: Determine Technical Requirements—Verify required static torque and calculate thermal heat dissipation based on load inertia and cycle rates.
- Step 3: Choose Mounting & Voltage—Select corresponding coil voltage and configuration for motor braking.
HOW TO ORDER
- Specify Part & Model: Order using current part number 5370-169-218 (replaces original part number 5370-169-062) or model EM-50-20MB (24 VDC).
- Select Power Supply / Control: Choose an appropriate Warner Electric DC control/power supply matching the 24 VDC coil requirements.
