Product Profile of Industrial Grade Direct Current Motor

Industrial Grade Direct Current Motor has a linear characteristic of voltage and torque and has constant and controllable speed over various loads. The Motor runs practically constant speed, regardless of the load and is the type generally used in commercial practice and is usually recommended where starting conditions are not usually severs. The Motor is designed in such manner that ensures that the speed of the shunt-wound motors may be regulated in two ways, first, by inserting resistance in series with the armature, thus decreasing speed and second, by inserting resistance in the field circuit, the speed will vary with each change in load; in the latter, the speeds is practically constant for any setting of the controller. The Motor provides the starting torque required for moving large loads and can be used for mixed load applications. The Motor has steel made frames that ensure good strength and ventilation is provided by strong fan. The Motor has the feature that in case of excess heat due to low speeds, blower mounting arrangement is provided for necessary cooling and has separate excitation. The Industrial Grade Direct Current Motor has bearings and their internal clearances are based on load carrying ability, thermal stresses and speed range consistent with ample bearing life.

Key Features of Industrial Grade Direct Current Motor

• A linear characteristic of voltage and torque and has constant and controllable speed over various loads
• Runs practically constant speed, regardless of the load
• Used in commercial practice and is usually recommended where starting conditions are not usually severs.
• Designed in such manner that ensures that the speed of the shunt-wound motors may be regulated in two ways, first, by inserting resistance in series with the armature, thus decreasing speed and second, by inserting resistance in the field circuit, the speed will vary with each change in load; in the latter, the speeds is practically constant for any setting of the controller.
• Provides the starting torque required for moving large loads and can be used for mixed load applications.
• Steel made frames that ensure good strength and ventilation is provided by strong fan.
• In case of excess heat due to low speeds, blower mounting arrangement is provided for necessary cooling and has separate excitation.
• Bearings and their internal clearances are based on load carrying ability, thermal stresses and speed range consistent with ample bearing life.
• Armatures are built using quality grade steel laminations, securely insulated from each other and clamped together under high pressure ensuring low heating losses
• Coils and wire-winding is strictly as per insulation class b.
• Armature is dynamically balanced to precise grade using computerised balancing machine to ensure low vibration operations.
• Utilize top-cushioned brushes for low-vibration operation
• Brush holders are extruded metal
• The constant pressured springs do not need adjustment.
