Product Description:

The MOT-FC-ET2-B35-225M-4-5CB- 45-C3T-HOY is an Induction Motor by Bosch Rexroth. It comes under the family of MOT Induction Motors series.

The MOT-FC-ET2-B35-225M-4-5CB- 45-C3T-HOY induction motor uses a standard cooling method defined by IEC to maintain its housing temperature. The thermal tolerance of the motor winding insulation is class F which means it can handle a maximum temperature rise of 105°C, with a total allowable temperature of 155°C. It is designed to operate on a 50 Hz power supply which is a standard in many regions such as Europe and Asia. The motor is 93% efficient at full load and only 7% of electrical energy is lost as heat which acknowledges its efficiency and it is categorized in the IE3 or IE4 efficiency class. It is able to reach the highest speed up to 2800 rpm which is a normal speed for induction motors running at 50 Hz. This motor generates 37 kW of power. The MOT motor draws 67 A of current to generate 238 Nm of torque at shaft end. This model has 2 pole pairs.

The MOT-FC-ET2-B35-225M-4-5CB- 45-C3T-HOY induction motor weighs 328 kg which indicates a large frame size—likely several kW in power rating. This module mounting type is B35 which combines both foot mounting and flange mounting and offers flexibility as it can be bolted down at the base and secured via the flange. It can produce the maximum torque up to 667 nm during startup or overload. While the highest current the motor will draw under peak load or startup is 202.5 amperes. It is designed to run at 400/690 volts which is typical for 3-phase industrial supplies.

Frequently Asked Questions about MOT-FC-ET2-B35-225M-4-5CB- 45-C3T-HOY:

Q: How does the B35 mounting type enhance installation flexibility in industrial setups?

A: B35 mounting combines foot and flange mounting, offering versatile installation in tight or customized equipment spaces. It reduces the need for redesigning mounting structures.

Q: Why is Class F insulation important in high-load motor applications?

A: Class F insulation provides better thermal resistance under prolonged or fluctuating load conditions. It increases motor lifespan by handling higher internal heat safely.

Q: How does IC411 cooling benefit the MOT-FC-ET2-B35-225M-4-5CB-45-C3T-HOY in dusty environments?

A: The totally enclosed frame prevents dust ingress while the external fan ensures continuous air circulation. This enhances performance and reliability in harsh environments.

Q: What is the impact of a 93% efficiency rating on energy consumption?

A: High efficiency means minimal energy loss, resulting in lower electricity costs. It also reduces heat generation, minimizing cooling demands.

Q: Why is a maximum speed of 2800 rpm ideal for many industrial drives?

A: It provides a good balance between torque and rotational speed. This supports a wide range of mechanical processes efficiently.
