Besides standard production, C.M.E. S.r.l. also produces both single and three-phase brake motors with single or double polarity. The bodies of these brake motors are identical to standard motors’ ones, but they have a longer fan cover because, besides housing the fan, it must also protect the brake assembly.
The brake is activated when the power supply is cut off.
When the motor is running, the springs are compressed by an electromagnet powered by the line voltage. When power is cut off, springs are released and they push (with an adjustable intensity) against a cast iron or steel plate which, in turn, presses against the friction disk.
How to choose a brake motor?
The electromagnet can be operated by alternating or direct current. Normally the electrical brake connections are set in the motor terminal box, but, upon request, they can also be applied to a separate terminal box, for a separate power supply.
When choosing a brake motor, clients should take into consideration many parameters to identify the necessary braking and motor dimensions:
• The desired speed of braking
• The number of start-ups/hour
• The turning force applied to the shaft (which requires braking)
CME srl produces three types of brakes:
• “K” TYPE BRAKE (powered by direct current)
• “AC” TYPE BRAKE (powered by alternating current)
• “S” TYPE BRAKE (decelerator)
