Electronically commutated ECM motor
The ECM motor has been designed to allow the motor to deliver more power with lower input watts. This transforms into cooler running operation which results in fewer failures. Less efficient shaded pole motors are often used in original equipment to cut costs. Fewer BTU's in the system means less work for the compressor and reduced compressor wear for even greater savings. while shaded pole motors do allow some small savings in purchase price, the savings are quickly absorbed in electric bills at today's high power costs. Using the ECM motor as in new equipment or as a retrofit to replace shaded pole OEM motors this can save the user up to 65 percent in energy usage.
The advantages of energy saving ESM motor for refrigeration:
1)Minimized space required due to compact design.
2)Reduced mounting depth due to optimized design allowing more room for you goods.
3)Simple speed control or more complex closed-loop control options can be integrated at competitive cost.
4)60% less energy is needed than with comparable motor systems.
5)Minimal heat load due to extremely high efficiency.
6)Optimized impeller design with extremely low acoustic noise.
7)Maintenance-free and high-quality ball bearing for extremely high service life.
8)Increase in service life due to humidity-proof design specially developed for refrigeration.
9)When servicing, fast, easy and cost-effective replacement due to existing plug connection.
10)Maximum moisture protection with the IP65.
