smooth starts reduce your costs

Efficient torque control ensures an ultra-smooth start with constant acceleration. Reduced start currents and mechanical stress means lower installation, energy and maintenance costs. Torque boost can be used to overcome initial torque peaks when starting, for example, a loaded crusher.

 

protect your process and maximize efficiency

A built-in shaft power monitor protects your process from damage, downtime and inefficiency. It reacts immediately if a crusher is jammed, a pump is running dry or a fan filter is blocked. Any deviation from your selected load levels will result in a warning or a quick but smooth stop.

 

smart stops - smooth or quick

Emotron MSF offers efficient solutions, whether the need is a smooth or a quick stop. A linear stop of a pump eliminates the risk of water hammer. No motor-controlled valves are needed. Built-in braking functionality ensures quick and safe stops of mills and saws without mechanical brakes.

An Emotron MSF is used to provide a torque controlled soft start and soft stop on an odor-control-fan application.


programmable inputs increase flexibility

Four programmable inputs offer great flexibility. The rotating direction of a fan can be controlled by programming two inputs for start left/right. No external PLC is required. You can connect an external alarm signal to stop the motor if a problem occurs. An analogue sensor can be connected directly to the Emotron MSF to control the start and stop levels of a pump.

quick and cost-efficient installation

Installing an Emotron MSF is quick and cost-efficient. There is no need for the additional equipment often required – DC brakes, motor protection relays, mains failure relays, load monitors, meters, displays, or switches. Everything you need is included in the Emotron MSF unit.

 

Starting currents reduced by +20% versus reduced voltage Soft Starts

more than just another soft start

With torque controlled starting and stopping, and a built-in patented shaft power monitoring feature, the MSF's ability to provide control and complete protection of your applications is unparalleled.

The MSF is among the most advanced Soft Starts available. Unlike previous generations of electric Soft Starts, the MSF starts and stops the motor using the torque controlled ramps. This principle not only provides ultra smooth starting and stopping, but also lowers starting currents by an additional 20% versus reduced voltage Soft Starts.
