Frequently Asked Questions

What speed does this 4 pole brake motor run at?

A 4 pole electric motor on a 50Hz supply typically has a synchronous speed of 1500rpm, with the actual full-load speed usually slightly lower. This model runs at approximately 1460rpm under load.

What is this 5.5kW brake motor commonly used for?

This motor is commonly used on conveyors, packaging equipment, geared drives, handling systems and other machinery where controlled stopping and holding torque are needed in a compact IEC motor format.

What does B14S mounting mean?

B14S is a standard IEC motor mounting arrangement. This version is supplied as a B14S Face Mount configuration to suit machinery requiring that fixing style.

What should I check before replacing a 5.5kW brake motor?

Before ordering, check the power rating, pole count, frame size, B14S Face Mount, shaft dimensions, supply voltage and brake voltage so the replacement matches your existing motor and application.

Does this motor include a hand release?

Yes, this brake motor is fitted with a hand release, allowing manual brake release when needed during installation, maintenance or equipment adjustment.

Can this motor run on an inverter drive?

Many industrial brake motors can be used with inverter drives, but suitability depends on the application, duty cycle, switching frequency, brake control setup and cable length. It is best to confirm the exact operating conditions before use with a VFD.
